Owner reviews for spark plug

Brisks are throwaways that need regular attention by either regapping them every few thousand miles or replacing. You can run NGK 7437-9s for 20k in a stage 2 car without touching them. There's a big price difference so you get what you pay for.

if you want some good plugs, get some denso IKH24, they are 1 step cooler than stock plugs.. I change mine out every 20k miles..

My plugs seem to still be running great, only have about 35,000 kms on them.

Did my plugs 4 months ago with NGKand they still feel great.

I run NGK BKR6E's in my rabbit. I have had the best results and longest life from the NGK plugs. To the point that is all I run in any of my cars! LOVE them!

IKH 24 plugs with stock coils work just fine. No cutout, rough idle or misfire.

Replaced stock with denso ihk24.

i am using pfr7b. maybe coincidental but my 3000-6500 logs always run a few milliseconds faster. only problem with .028 are some few intermittent low rpm misfires.

after putting the new ones i changed all the spark plugs too, to fit them properly with new wires. but the car runned roughly, so bad..and when mechanic unscrew the new spark plugs to see, they were carbonized black, with just a ride around.

I unknowingly sourced (6) NGK ILZKR7A Spark Plugs a year ago from eBay and installed them at 60K miles on my 3.6 VR6. I found out last week that the plugs were fakes. About a month ago I started getting random misfires. After detailing the issue in this thread here: https://forums.vwvortex.com/showthr...VR6-Cyl-2-Misfire-When-Taking-Off-Quick-From-Stop-Suggestions&highlight=Misfire I pulled the spark plugs and checked them last month and noted the gap was pretty far out of spec (weird for only being a year in), so I gapped them and reinstalled and the problem went a way for a few weeks. Last week I had another misfire, so I chalked it up to a bad batch of spark plugs and resigned to buy and install a new set.
