Emissions Disclaimer

• This item does not ship to California.

Specs and Features

• Universal fitment, bolts to any standard TiAL flange with no re-welding required
• For use on turbocharged and supercharged applications, including Paxton and Vortec supercharger setups
• Body and all internal components CNC-machined from 6061 aluminum alloy
• 1.98 inch (50.5mm) valve diameter, the largest in TiAL's lineup
• Flows up to 60% more air per cycle than the original TiAL BOV design, the highest flowing 50mm BOV on the market
• Rated to support up to 1,800 horsepower on a single valve
• V-band design aluminum mounting clamp with stainless steel hardware for a clean, corrosion-resistant appearance
• Viton O-ring valve seal, clamped in place to prevent sticking to the seat or pulling out
• PTFE-lubricated, hard anodize-coated valve stem and guide for long-term wear resistance
• Machined aluminum banjo-type air fitting and bolt with oversized 10mm hose barb for quick actuator response
• High temp silicone Nomex-reinforced diaphragm in the actuator for long service life
• Aluminum weld base mounting flange included with each unit, cut for standard 2-1/2 inch pipe
• Available in 2, 6, 8, 10, 11, and 12 PSI spring options, including a dedicated spring for supercharged applications, spring ratings reflect idle vacuum level rather than boost pressure
• Available in black, red, purple, silver, and blue anodized finishes
• Requires a 1/4 inch inner diameter direct boost reference line to the intake manifold for proper operation, smaller lines or T-fittings can cause delayed response
• Removing a factory electronic diverter valve in favor of this externally actuated valve will trigger a P0035 check engine light on vehicles with OE electronic BOV control, this does not affect drivability or performance

Product Description

Q is the first revision of the original TiAL BOV. The Q bolts up to any standard TiAL flange, no re-welding.  This is the highest flowing BOV on the market.  It's offered with a variety of springs for different vacuum levels and a special spring specifically for supercharged vehicles

Disclaimer and note

If your car came with a factory electronic blow off valve from the factory and you're swapping to this externally actuated TiAL Q, expect a P0035 check engine light to come on. This is just the factory computer noticing the electronic valve is no longer there, and it has no effect on how the car drives or performs. If a clean dash with no check engine light matters to you, an electronic plug-and-play valve would be a better fit than an external valve like this one. For boost reference, run a direct 1/4 inch line straight to the intake manifold rather than tapping off a smaller line or a T-fitting, since anything smaller will slow down how quickly the valve responds to boost changes.
