Side by Side Comparison of: NGK

fit my Sportsman 500 as advertised.

Ngk quality, nothing more need be said. I use them in all 3 of my cars.

I'm a NGK fan, they just work well!

NGK all the way, way better than elcheapo champs

Fit our 2008 Subaru Outback with the non-turbo 2.5. After install noticed an immediate improvement in power, throttle response, and a smoother idle. Good product.

Restore Power with these new plugs

Perfect drop in replacement for Hyundai Elantra 2006. You will want an extension for your socket wrench, and probably a gap tester just to be sure. I tested four of these and they all came in a 1.1mm. Popped them into the car, and have had no problems yet. Awesome replacement!

After years of owning Subaru's, I've learned that they can be very finicky with what spark plugs and spark plug wires are being used on them. For reasons I can't fully articulate why, Subaru's run best when using NGK spark plugs and plug wires.I purchase this kit of NGK plugs and plug wires after discovering I had one cracked spark plug and another one that was coated with oil and not firing right. All four were Bosch and I replaced them with these NGK Iridium plugs and immediately I received a power boost in the car and it worked like an absolute charm! I'm making every effort to go through and replace the plugs in all of my Subaru's with NGK's and NGK wires.

I've used NGK plugs solely for the past few years. I swap them out every 50K +/- miles and they come out in good enough shape to use again... but if they are already out, I'm just going to replace them. *knock on wood* I've never had an issue with them and will keep on buying them.

This is the 3rd time, in 12 years that I have replaced the spark plugs on my 1999 Miata - Sport Trim, aka Silver-Bullet.14K Original Miles and when I was prepping it for the upcoming Safety Check, I immediately detected a audible "miss".Just don't ever take it out very often on the road anymore, simply because I don't trust parking lot's and other drivers, especially the oneswith beat-up jalopies!4 cylinders = 4 plugs. Replacement was dead simple, easy and required no special effort, like the #2 Down O2 Sensor I replaced 5 years ago.Luckily, the Gap's were all factory gauged and I did re-check them x 4 ... all within the Gap of .043 (1.1mm), and 3/4" (19mm) ...RESULT - Nothing but the perfect tone of a harmonious, subtle rumble ... like it was new ... all over again. WHAT a Difference.I took it for a spin and it ran even more Smooth & Nimble than before.These NGK Iridium IX Spark Plugs are not only highly-recommended, but they are a MUST INSTALL ... Pronto!Get Some Today!https://www.amazon.com/dp/B003BUCKQ8/ref=cm_cr_ryp_prd_ttl_sol_17BTW - I'm planning on Selling this Collectable Miata sometime this year.

Nice spark plugs for my 1996 Mazda Miata. Over a 1000 miles since the install and working well. I didn't use any anti-seize being that NGK says not to use, and that the threads have some sort of chemical lining/coating not requiring it. Also, I've heard that applying anti-seize may affect the torque resulting in over-tightening. The torque setting was pretty low in the first place for this car 11-17 ft/lbs.My Miata has ~250,000 miles and still running like a champ. The beast loves these plugs.

Though the manual says that you should use only twin ground electrode spark plug, NGK (5464) BKR5EIX-11 Iridium IX Spark Plug are the best suited for 1998 Toyota Corolla LE. The idling has improved drastically and the running. of the vehicle is so smooth, my wife sitting in the passenger seat expressed her satisfaction. Besides the plug comes with preset gap. '11' at the end of the plug code stands for 1.1mm (0.044-in) preset gap. It was so easy to install the plugs by lowering it in to the well with out dropping them with the help of Gear Wrench 80546 5/8-Inch x 6-Inch Swivel Spark.(magnetic) that I bought with the plugs. The matching is done very well by the Amazon if you only feed them with the correct description of your vehicle it will be a perfect match. I highly recommend this product.The plugs that was in the vehicle were Denso (3194) K16TR11 Traditional Spark Plug with Twin Ground Electrodes made in Japan appears to be the manufacturers initially installed plugs.Martin10/25/2015

This is a resistance plug, not a platinum plug so it will need to be changed out in 30K miles or so. Not a problem, but I didn't realize.

good

Photo online shows gold version, I called NGK tech support and they told me this is a very old plug. Although they do not expire, the newer silver model (such as the one I received) has a new and improved anti-corrosion coating known as trivalent plating. This was confusing to me, and so I thought I would enlighten others.

Meets expectations. They are not gold in color.

works fine but my 97 4runner needs double ground plugs, i made a mistake of buying these single lead ones, 4 stars because it shouldn't have been a fit for my car according to the car match algorithm but i should've known better

Installed on a 2003 Nissan Xterra 6-cylinder. They installed like any other spark plug I have put in cars/trucks over the many years. However, these plugs need to be tightened more snug than any plugs I have previously used.When they were initially installed the smell of raw fuel was coming into the cab of the vehicle. After re-tightening every plug the smell went away. I really cranked down on the plugs when they were tightened the second time a lot more than I like to do with aluminum heads. I was happy the smell went away, but not very comfortable with possibly stripping the threads in the cylinder head. Either way, the performance is just like stock plugs and is no degradation in fuel economy.

I replaced 4 of them. Working great.

Great plug

So far so good. Good performance. Did not greatly improve anything but they work well.

Came on time, they are for a 2008 Prius. An article supposedly indicated an increase in gas mileage,(I'm getting greedy), but if anything we're getting slightly less. Run well, no glitches.

I bought these for my girls 05' Toyota corolla.......to replace at 100,000 milesThe ones I removed looked good after all those miles.......so I can only imagine that these will be trouble free for another 100.000!The car starts easier now.....less cranking

Installed on a Early 00's Subaru Outback 2.5 liter, and installation was simple enough. Paired this purchase with NGK Plug wires and a Felpro Valve cover gasket kit. Arrived in perfect shape and the fit was correct.

Good but keep in mind these are COPPER plugs so won't last more than 50k...

good

Good product

hard to gap, they came at 43 and needed to be 31-32

Buyer beware as this item was very expensive. It pays to comparison shop.

Ok

Worked fine.

I ordered the wrong part.

I just can't say that I "LOVE" an spark plug or any other inanimate object and think you should change the top 5 star rating to "exceptional" or something other than "LOVE"!

Product OK delivery slow

Bought early this week, got yesterday, installed, and broke it broke off inside my head with a torque wrench at about 50lbs.Would like if seller contacted me.

I have a nissan frontier after i install it it wont give me more power like my old sprk plug. I will come back to Double Platinum..

actually i like NGK product because the try to make spark plug work properlyi have already bought lots of their product but this time i got damaged product electric at service center said that two out of six had a misfirei am really disappointed

there not nickel tipped electrode provide a longer plus life they are cheaply made junk in a nice package.

before buy this plus i checked the Fit status and was given the confirmation that it fits my Toyota Yaris 2013. that was in January. as i write this review in June, the Fit status tells be it doesn't suit my car. Thats like being tricked into buying. In fact i am not very surprised because as soon as i installed these plugs, my car started throwing out some very worrying codes( P0420) and my MPG dropped significantly. i replaced them with the old ones that came with the car( used) and the MPG improved though the code appeared. in all i wish i could get my money back but i guess it's too late now. i wasted my money because i was tricked by the seller

wrong produce and can't sent it back !!!!!!!!!!!

Im sure the product would be great but unfortunately Amazon said these would fit a Toyota Corolla 2011. They do not. I ended up wasting my money.

Wrong item

it is not for the 1999 toyota corolla CE 1.8 car.. TWIN ELECTORDE PLUGS ONLY

Not sure why and how the amazon catalog showed the spark plug as compatible with my car and later on when I received the product it did no fit in my car, I immediately went back to the catalog to double check the order and the product details and guess what?, the product now does not fit as per the catalog, now I have to purchase again more spark plugs...Great!

It advertised it fit our 2002 honda foreman. It did not... Wasted my money. The tip on the plug was different.

Amazon stated this plug worked with my 05 legacy gt limited. It in fact does not. The plug here is meant for the non-turbo'd 2.0 motor not the 2.5 turbo. You can imagine the trouble this could cause.Had to have the car towed to the dealer after the motor began to run poorly, heading to a stall in drive and shutter while in park. Dealer said no long term damage was done but that it could have been much worse.Likely no fault of the NGK plug but Amazon's system for getting it wrong. Either way I am leaving this as a 1 star in hope that people searching will wonder why 1 star and save themselves the expensive troubles I faced. While Amazon covered the cost of getting my car fixed and inspected at the dealer, I see 2-3 weeks later their system still says it works. Dealer made it very clear these plugs were wrong and showed me the difference. It's visible. We spend about 10K/year on Amazon but I will likely not get auto parts again. Was my first time.
