Owner reviews for spark plug

And, before you get too far, are you replacing with the right plugs? I presume it’s the 2AZ 4-cyl since you’re not asking us how to get to the back plugs. The right ones are the Denso Iridium Long Life or the NGK Laser Iridium.

To be honest the last plug VW went with , the 101905601F (OEM clones Bosch copper nickel FR7HE02 Or NGK ZFR6T-11G (5960) Copper Nickel, Beru BRU-Z272 copper nickel ) for the 2.5 is best. It’s one shade cooler and will have less spark knock. You have more timing.

I forgot to mention that I installed brand new pre-gapped NGK spark plugs two years ago

I like NGK, but you can't go wrong using what the manual calls for.

Champion and NGK have good reputations.

Ngk’s are hard to beat.

I have Seat Leon FR 2.0 TFSi 2007 DSG F1 165k KM, stock engine, and stock map, only things I've done since I purchased it were: spark plugs NGK

Bought mine from rock auto; got the Bosch ones since the NGK’s are really only recommended if your car is tuned

Auto lite is garbage now. NGk is the way

when I worked for a Chevy dealer we hated Bosch plugs. Chevy's just don't seem to like them, they were often the culprit in misfire diagnosis.
