Spark plugs

[chrism]

Ive been told I need heat 9 plugs for my car when Im up towards 2 bar.
Running 8´s and never had any problems.

Are any of these okay?

I found NGK BCR8ES pretty excellent for F/I engines and many on here use them. Since you need heat range 9 for your 2BAR !!! of boost, you could always try BCR9ES

Having difficuilty finding them over here.

I have found BCPR9ES11. Will they be just as good?

Aren't they for leaded petrol or something like that? - When I was looking at plugs for my other car the ~11 was (or wasn't, I can't remember) required for leaded fuel.

As far as I could see, theyre used on high bhp saabs over here. Unleaded and E85.

Yeah, I got that the wrong way around. - In the Hyundai manual BKR5ES-11 is for unleaded fuel and BKR5ES is for leaded.
It might explain why the "standard" version is getting hard to find; it's been superseded as they don't need to support leaded fuel any more?

Doesn't the P mean projector ie it sticks further out into the chamber. Whether this will cause you any problems I can't say. The 11 is just the gap - 1.1mm, so regap them.
