I’m selling as a full turnkey intake to pan. 8500$ cash. The engine is still in my car so you can hear run. It was dynoed made 423whp before the transmission in my car failed so didn’t get peak number’s but it should make mid to high 400s. It doesn’t have milage on it other then initial test drive and dyno because of transmission issues it’s just been sitting. Iv decided to part the car out instead of wasting anymore money on it. Serious buyers only please as I don’t want to pull the engine and have a no show.
