Bread and Butter
It is Grimmspeed, nothing else needs to be said…
This is Grimspeed’s bread and butter, nobody asks “what solenoid should I run” because everyone runs the Grimmspeed solenoid without question… because it is the most reliable and the best on the market.
I don’t need to go over how great they package it and how the finish on it is perfect, that just comes with their products.
grimmspeed all day
So received the product in a timely manner and the install was easy and fast. Tune was done recently and my tuner mentioned that having the modifications I did grimmspeed intake charge pipe and 3port ebcs and a few other brand parts my 15+ wrx made cleaner power and boost and made the tune a breeze and also was told I made the most power he had seen for 15+ with the mods equal to everyone else. Grimmspeed for the win
