2005 WRX ppp Imprexa

Are these Iradium plugs better than the standard PFR6B plugs? Anyone tried them?

Better than a std plug ?? Difficult to say as the differences between them are so small.

They certainly wont be any worse. Ive got a set waiting to go into my car, have used them on other cars without any issues.

 

Cheers bud appreciate your reply, I'll order them today
