92-97 Subaru Alcyone SVX TSP G-Series Racing Coilovers

I recommend. I had a problem getting a suspension for my old Subaru and they pulled it off and sent in a timely fashion. Great service.

EG33 Intake Manifold Phenolic Spacers

Josh Bettencourt

came through in a big way with some Phonalic intake manifold and throttle body spacers for my 95 SVX. i was doing a complete engine reseal, was on a time crunch, and decided last minute I was going to order a set. I was able to get them within the week and get my car done and off my lift within the time constraints i was given. thanks again John!
