yep was bloody hard though prob never been replaced.

Hi Ian. Need your help again. Why does my car need new spark plugs every 3 months or so. I have tried iridium and ngk plugs both don't last long and the car starts to struggle to accelerate when they start to fail on me. Once I replace them all goes back to normal again..

 

And what are your views of boost creep was on the freeway today and had to lower my boost cause the car was surging like pre-ignition ping once lowered the problem was solved and as expected in doing so less grunt off the freeway after woods.
