Default Changed Spark Plugs

I just changed my spark plugs. they were quite overdo for a change. I put in some Denso Iridiums this time. I had NGK Coppers one step colder installed before. They were pretty discolored. Haha. They were gapped out to .045 on all 4. I was probably blowing my spark out at high boost with that. Hence the missfire codes i had earlier this month. haha. Just wanted to throw that out there.

Yep, that would probably do it! How many miles did you have on them?

i had like 20,000 on them. i have an 18G with supporting mods. I put off changing them, suppose to with the plugs i had like every 10,000.


Well its not that hard to change them but it does take some time and the right tools. It takes a bit the first time u do it, but after u do it once it will only take u have the time.

For plugs i guess it probably depends on if your still stock or are heavily modded. If you have a turbo upgrade and all the supporting mods then you probably gonna want to go with some high end plugs. I Got some Denso Iridium which are like 65 bucks for four of them. they last a lot longer too though.

the best plugs are coppers. I use NGK BKR7E Stock # 6097. The only downside is you have to change them every year or 10k miles which is nt that bad. Something for me to do during summertime.

I'd just throw the stock plugs in. It's not hard to change the plugs, just time consuming (if you've never done it before).

There was alot of discussions on the denso iridiums in the wrx's regarding kernal blow out a few years back. I don't think it was anything definitive, but take a look if you start getting some stuttering or hesitation. Primarily this was on modded cars.

Is one step colder a good idea for stage 4 WRXs?
