Holley is pleased to announce the release of several new STS Turbo products – direct-fit intercoolers, wastegates, blow-off valves, air filters, and air-filter wraps.

DIRECT-FIT INTERCOOLERS 

STS Direct-Fit Intercoolers are a fast, easy way to add air-to-air intercooling for better control of air intake temperatures and more horsepower. Available for numerous late-model applications, they're made of 6061 aluminum, polished, 100-percent TIG-welded, and feature a bar-and-plate design.

WASTEGATES 

STS Wastegates feature a one-piece stainless steel valve for maximum reliability and a proven silicon-Nomex diaphragm for max reliability. They're offered in two configurations – a 38mm version that's ideal for street and racing applications (specifically those with two-bolt flanges) and a 40mm design that's perfect for fitting into tight spaces. Both come complete with a locking ring-removal tool, 2x1/16-inch blank plugs, and 2x1/16-inch vacuum nipples.

BLOW-OFF VALVES

STS Blow-Off Valves are 50 percent lighter and 25 percent smaller than ordinary blow-off valves and still flow more than 330 CFM. Built with trusted Turbosmart components, they feature a unique collar design, a hard-anodized valve guide and stem, a positive-sealing valve seat and a proven silicon Nomex diaphragm for maximum reliability. The quick-release V-band collar makes installation and removal a snap, and dual vacuum ports give you multiple options for line-positioning.

AIR FILTERS & FILTER WRAPS

STS Air Filters come with high-flow cotton media that's washable and reusable for years of trouble-free service. The specially layered and oiled media traps dirt particles and let engines breathe deep for maximum power. STS Filter Wraps keep out dirt particles and street debris as small as five-thousandths of an inch, and the pre-filters are run dry, which means no oils or additives are required so no dirt sticks to anything to rob power.
