Reviews of NGK spark plug

Here\u2019s where I\u2019m at after about a year of ownership. A few of these were just cosmetic fixes. I\u2019m at ~$540 total. Spark plugs, replaced with NGK BPR6ES - $20.00

My brand new out-the-box WEN 3500 would barely start until I tossed the Torch and replaced it with an NGK. It now runs as designed. Too many others have had similar issues and that's why Torch is widely regarded as junk.

Look good …. Just try to get denso or ngk

Switching fixed my ignition issues after having Autolite for only 2 days after purchase switched them to NGK and resolved my issues

Just swapped all four plugs in my 2013 Kia optima EX 2.4l for ngk iridium’s, still had the original sensor plugs in at 91k so honestly not sure how I didn’t have any misfires but have had a rough idle

They are very picky with their spark plugs so you are limited to NGK which is oem.

I recently put in NGK LKAR7BIX-11S (93501) and some cheap amazon coils. A coil failed and I just replaced it all to be sure.

Put in NGK ILKAR7B11 (4912) around 186k miles. I've burned so much oil and did a piston soak at 205k~. I scrubbed the tips with a wire brush but it didn't do much. Lots of carbon. I really don't notice a difference.

worked for nissan and honda as a tech and i will always recommend ngk laser iridium spark plugs. use them in my own vehicles and perform well

Replaced the torch with NGK BP7ES. Non resistor and run exclusively on propane. All I can say is my WGen 11500 starts every time on the first or second turnover. Torch it would go anywhere between 4 and 7 before cranking. I just know Torch plug sucks.

Swapped the spark plugs w new OEM NGK ones and 0 misfires 0 errors and car runs like new. espeacially notice a difference on start up and idles smoother
