S-MAX Blow Off Valves will increase the longevity of any turbo and improve performance. Both the SW300 and SL300 share the same mounting characteristics. They are both universal in fitment. They come with a single aluminum flange that could be welded on to an aluminum charge pipe or used with a silicone coupler.
The S-Max SW300 is the most unique blow off valve on the market due to its adjustability of sound. Just by simply aligning the holes you can alter the resonance to your preference. From a standard blow off valve to an ear piercing loud whistle. NO TOOLS REQUIRED!
