QUESTIONS & ANSWERS
Q: 2006 WRX fitment mason.davies.usn2780910 days agoAccording to the GSC Website, these are designed for all EJ25s with intake AVCS. I dont see any S1 grind cams for the EJ25. Is it possible that there is some sort of error with the fitment list? I would really like S1 cams for my 2006 WRX
