Spark Plugs

[gcas]

Does anybody know the best spark plugs to put in an evo 4??

Ngk bpr7 !!!!
Std if you change on service
Or fit iridium if you like but more costly

Bpr8es if the cars running higher than standard boost.

Really? Mine's using standard £17 NGK plugs and running over 600bhp @2.1bar...

Br8es? That's what I used to put in my Kawasaki kx 125.

Lots of people told me that the Plugs with R on them are crap and don't last long is this true?

But what plugs are they? I run 1.6 bar and havent had a problem for 2 year. Plus you can get em for a tenner.

Copper core ones. It ran like a bag of crap on iridiums at high rpm.

7 or 8 doesn't matter as similar heat rating. 8 is obviously higher and better for high boost/power cars. But 7's are fine. Its about getting the right gaps to suit your mods and level of performance. Iridium allow bigger gaps due to better spark but can have a shorter range at which they work. Hence steves problem at higher rpm

BR8ES or BPR8ES
Both awesome plugs.

How about for a 98' Evo V? Not too much aftermarket on her, just exhaust and intake.

Copper or Iridium NGK Bpr8es it sounds like?

 

[Steveyb_evo3]

Or br8es

 

[Steveyb_evo3]

I will only use copper

 

[Paully]

Sounds good Stevey, I'll pick some up then! What kind of wires do you use? I want to get those changed at the same time.
