Reviews of NGK parts For Business

I've use NGK products in American, Japanese and German vehicles for over 30 years with absolutely no problems at all. Note that NGK spark plugs come with a proprietary anti-seize coating on the threads, so no extra anti-seize is necessary at all.

I’m running NGK racing plugs # 4654 or R7437-9 no issues.

When I bought my 2008 VW Rabbit 2.5, it had 142K miles on it and I wanted to be sure I did a complete tune-up, not knowing its history. I bought the whole OEM unit which came with cover, gasket, bolts and PCV valve at a low price from Amazon. When I pulled the coils to replace the plugs, I saw that they were covered in oil from the leaking center section of the gasket, so I bought NGK coils to go with the NGK iridium plugs. When I pulled the plugs, I saw the tops were also covered in oil but the working end of the plugs were fine (Bosch plugs and the original coils). Replacing everything was easy and I torqued everything correctly. No more leaks and the car performs wonderfully on 87 octane.

The NGK 5690 is a clone of the Bosch copper nickel FR7HE02 it’s cheaper and runs great in a 2.5. It’s actually oem for 170hp 2.5. Change it at 40k. It’s the last plug VW put in 2.5s so it should be the best one. It’s one notch colder than the NGK laser platinums. The NGK 5690 will allow the motor to pull more timing and more power. For best results use 91 or above. It’s even in the owners manual.

My personal experience is that NGK brand for any type of spark plug is superior to others in all vehicles. I use the NGK iridium plugs in my Rabbit and my Honda cars. My older Miata had a wasted spark system and required a change interval of 30K miles, regardless of the plug, so I used the NGK copper plugs in it and there was no difference in performance at all.

I've been running the oem ngk's with the is38 and have never had an issue. They are gapped a little tighter per APR's recommendation but that's about it.

Ended up getting NGK.

I did the plugs around the same mileage in my 2014 CX-5 (2.5 liter), last April at 65,000 miles. Used the comparable NGK Laser Iridium plugs. Mine had some carbon buildup but all in all, they probably could have went longer.

I changed spark plugs to NGK laser platinum plugs with a 0.32 gap. The issue only arouse after I got the tune.

I'm Stage 2+ with r8 coil packs and ngk BKR7EIX and still get misfires. I'm not happy about it and I'm not sure what to do.
