Yea I searched and found a few results but non on the NGK TR55 plugs for the eco. Are these a good plug for a lightly modded engine?
NGK TR55

those are not proper length

1. For all NA use the stock plugs
2. For low boost use the srt4 champion plugs
3. For high boost use the NGK SRT4 plugs

Question, sort of regarding the same thing. Rk sport makes a berrylium copper ignition spring upgrade for the ecotec($30). They claim it provides 80% less resistance. Does anyone have any experience with this. Also once installed does it make sense to start using a higher octane fuel. Thanks.

they work ok


the only reason to use high octane gas is for nitrous , boost , or high compression

Iridium Spark Plugs are the way to go, our spark plugs are very cheap and ugly. Not by the way they look, but how crappy they looked when I pulled them out. I noticed a lower idle, increase gas mileage, and a better ride. $30, totally worth it.

Again TR55s are not a proper length plug and you can cause damage to your head by running them

Yup! LOL!! Has anyone tried Bsch Platinums on the Ecotec? I know when I had my 2000 2.2L they ran awesome and that is what I was going to change out my stock plugs with on my '04.

lol bosche sucks. you were lucky your car didnt detonate. they are horrible gimmic plugs, the spark travels to the closest metal tip it can, why would it help to have 4 of them? stock plugs run great. and dont tell me i dont know what im talking about, i used to have bosche plugs, but i got smart and put the old ones back in, and walah my idling problem and throttle response issues were resolved.

But i bought the NGK iridiums to try them out so we will see. I have stockers for backups just incase






Re: Ecotec spark plugs?

upon further research i have found that the NGK's are a bad idea! the reach is .708 (18mm) STOCK IS 25mm!!!
