Owner reviews for spark plug

My feels like it’s running brand new with 100k plus miles ????

I just got Bosch ones for my 2gr in the Lexus. Worked well, no complaints. And they weren’t badly priced

Only use NGK.

We have a 2014 (F56) 2 door, Cooper S, manual. I bought it for my kid pre-pandemic and we've put about 50k km's on it since buying it. Zero issues. We do our own simple maintenance, oil changes, spark plugs, brakes etc and it's no different than any other car really in that respect.

I would go for NGK. Using this brand on all my cars so far, I would not risk a switch. Although a compatible Denso will be equal for the short/mid/term.

At 101k miles I recommend that maintenance package if it hasn\u2019t been done before and you\u2019re not mechanically include. Spark plugs were $80 for NGK plugs and I have diag tools + experience to inspect my own so cost is $100.

The plugs EQT recommends are compatible. I’ve been running Denso 5749 plugs for over 10k without issue

I pulled Denso plugs out of my truck and put NGKs in. Is there a difference? Maybe... But experience with Japanese industrial equipment says that Japanese engines like OE ignition components. NGKs are cheap and readily available.

I bought 2 sets of NGK Irridium plugs from Amazon sellers that turned out to be counterfeit. The electrodes were completely worn off with 60k miles on them. They are supposed to last 100,000 miles. The cars were misfiring and had spark knock.

I learned that proper, very hard to tell, NGK knock offs even existed after I was bitten by fake ones off Amazon. The porcelain around the center electrode broke off and went through the engine.
