Nine times out of 10 in life, you don’t want to be the person known for blowing things off. But when it comes to your turbocharger, you can do all the blowing off you please thanks to our selection of blow off valves. A turbocharged engine builds up a lot of air pressure in the intake when it’s busy improving your 0-60 time, and a blow off valve is important for relieving that pressure and reducing failure rate. Modern Automotive Performance has a great selection of blow off valves and accessories for releasing that pressurized – accompanied by that distinctive hissing sound you love – and getting your engine ready for the next charge.

Whether you need a blow off valve for a Subaru WRX, a Mitsubishi Evo X, a Ford Mustang EcoBoost or numerous other performance vehicles, we have what you’re looking for in our collection. We offer a variety of port sizes and spring pressures to give you the right amount of pressure relief with your favorite racing-style hiss. Pick up a BOV or BPV for an MPI supercharger, or choose an adjustable dual port blow off valve that can be configured up to four different ways. Each valve is made from durable mild steel, stainless steel or aluminum and is available in stylish colors that accent your ride.

In addition, MAPerformance has a number of blow off valve adapters, which depending on the manufacturer, can be used to either mount your valve to the stock piping or redirect where the air pressure releases. We also stock block-off plates, spring tuning kits, gaskets and other hardware to tune your blow off valve to perfection. With brands such as Turbosmart, Boomba Racing, Go Fast Bits and Greddy in stock, you’ll know you’re getting a quality part. Yet you’ll pay a blow off valve price that any gearhead can afford, with free shipping on qualifying orders to boot. Call or email us today to learn how we can help you blow off the competition!
