Owner reviews for spark plug

My grandfather use to say that Champion Spark plugs killed more American pilots in WW2 than the Japanese did. NGK for life.

I want to say that NGK is OE. Regardless, I got NGK and haven't been disappointed.

Just picked up another 4 Ruthiums from rock auto, can't beat $8 a plug.

I did Denso 3297 from RockAuto. They work great.

I've always used the Denso SK20R11 plugs in mine and been pleased.

Ill say this, i got a set of 6 high quality ngk platinun tips for like 60 bucks

I buy the NGK laser iridium spark plugs. About 100 dollars.

What plugs you're using may help. In my experience not all plugs are created equal. Brisk, for example, last maybe 5-10k miles before they're garbage. Whereas I can run NGKs for 15k+.

I was given an "offer" to have my spark plugs changed for $368!

Ive got the densos twin tips in a vxr at present. One thing i can tell you is they dont like heat!!! i recently had a small coolant leak and they would misfire. pretty low heat resitance i think. work fine on cooler engines.
