It is a direct swap for the OEM item and should take less than 15 minutes to replace. Suitable for stage 4, 5, 6 and 7 cars upto around 550 BHP. When I had this in my old stage 4 engine setup the car made a healthy 309 BHP (partly becuase of this part).
These items sell for £330 +P&P on eBay. Based on that I am selling mine for £280 + P&P.
