Spark plugs

[Edd]

What are the best or appropriate plugs (heatwise) to use for the following boost levels

1.4-1.7 bar

1.7-2.3 bar

and will these plugs still make the car run fine off boost?

cheers guys

Ideally want a set for each boost bracket but if a set will do up to 2.3 bar then that's cool

i had HKS S45i's in it before when it was running up to 1.4 bar

Would have thought that the s45's would be fine for that, bit of overkill for 0.8bar though :lol:

 

[Si..]

are you asking so you can get the opposite of what will work, to lose a bit more power. :lol:

Whichever type you get,remember the all improtant filling of the recess up with water afterwards.No point fitting new plugs if they're going to make your car go faster.In fact,get some for a Micra :lol: .
