Review on πŸ”§ MAC 35A AAA DDBA 1BA Control Solenoid B238300: Precision Engineering for Optimal Performance by Travis Caminiti

Revainrating 1 out of 5

Not for automotive use.

Installed on my WRX 05'. If professionally tuned, the boost pressure would not exceed 12-13 psi. My tuner informed me that those cheap MAC valves are not designed for use in cars, sometimes they work. Sometimes they don't. He told me to buy a Grimmspeed which is a MAC valve but they replace the internals with automotive quality spools and seals. Swapped EBCS and made 19psi with no problems.

Pros
  • Coil voltage: 12VDC DC
Cons
  • Some little things
