Not the best but i think its the cheapest and easily good enough for well over 400bhp. I’d probably say mishimoto is the best just looking at dimensions and build if you’re after the best though. ETS is really good aswell. A guy running 600bhp on the ETS one
Norris Designs do a really good intercooler rated at 925 bhp
This is our custom built in house intercooler which bolts on behind the stock bumper but requires cutting of the rear section of crash bar, it cools and has sufficient airflow for 925Hp. It features a superb Garrett Bar and plate core, not to be compared with a cheaper and inferior tube and fin cores offered by some others. This kit also comes with custom pipework to connect the intercooler all the way from turbo to throttle body. Made with lightweight and durable mandrel bent aluminium tubing.
