Evening all. This could be a numpty question but my bugeye wrx is going in for a service next week and I'm wondering if it's ok to have her fitted with a different grade of spark plug now so that I don't have to change them again sometime next year when I plan to uprate the turbo/remap etc. Thanks.

 

What are you running now and what you wanting to change them to?

 

Hi, presume they're just the standard grade spark plug. I'm planning on getting her up to around 300-325 bhp using vf34,sti injectors, remap etc.

 

Decatted already? If so should have PFR-7B's fitted.

 

AS micky says I would get the NGK PFR-7B's. Just make sure the gap is correct.
