Turbosmart BOV Kompact EM Dual Port VR20
The award-winning, truly plug-and-play blow-off valve upgrade for your Tundra, Sequoia, or Lexus GX 550 V6.
The World's First Plug-and-Play BOV
The multiple-award-winning Kompact EM Series is the first truly plug-and-play upgrade for your factory diverter valve. Unplug and unbolt your OEM valve, drop the Kompact EM in its place, and you're done — no adaptors, hoses, or extra assembly required.
Turbosmart took motorsport-proven billet valve technology and added an onboard proprietary solenoid and internal pressure control channels. The result: a simple bolt-on valve with full OE integration and control. No reference hoses, no separate solenoids, no fiddly bits.

✅ Lexus GX 550 Fitment — Verified
We've confirmed this valve fits the 2021+ Lexus GX 550, which shares the twin-turbo V6 (VR20) platform with the Tundra and Sequoia. GX 550 owners get the same plug-and-play billet upgrade — direct replacement for the factory diverter valve.

Boost-Balance Valve Technology
Plastic factory valves fail — they crack, leak, and lose their seal under boost. The Kompact EM solves this with Turbosmart's Boost-Balance Valve design: the more boost you make, the better it seals. Add a positive-seal O-ring on the piston face and full billet construction, and you get a valve that holds more boost and responds harder in any environment.

Two Configurations — Choose Your Sound
Dual Port (vents to atmosphere): Vents a portion of the charge to atmosphere for an audible blow-off "Pssshhh" while recirculating the rest to keep your OE mass-air setup happy. Pick this if you want the sound.
Plumback (fully recirculates): Routes all of the vented charge back into the intake system for a quiet, OE-style operation with no atmospheric noise. Pick this if you want the performance and reliability upgrade without the extra sound.
🔧 Installation — Bolt-On, Plug-In
Unplug and unbolt the OEM diverter valve, then bolt the Kompact EM in its place and plug in the connector. No adaptors, reference hoses, or separate solenoids needed. Full OE integration means no tune changes required.
⚠️ Fitment: 2022+ Toyota Tundra (V6), 2023+ Toyota Sequoia (V6), and verified 2021+ Lexus GX 550 (V6). Patented technology — USA Patent 10,781,745 / AUS Patent 2018253619.
FAQ
|
Does this fit the Lexus GX 550?
Yes — verified fitment on the 2021+ Lexus GX 550 V6, which shares the VR20 twin-turbo platform with the Tundra and Sequoia.
Is it really plug-and-play?
Yes. Unbolt the OEM valve, bolt this one in, plug in the connector. No adaptors, hoses, or separate solenoids.
Do I need a tune?
No. The integrated solenoid gives full OE integration, so no tune changes are required.
|
Dual Port vs Plumback?
Dual Port vents part of the charge to atmosphere for an audible whoosh. Plumback fully recirculates for quiet, OE-style operation. Both are the same billet valve otherwise.
Will it hold more boost than stock?
Yes. The Boost-Balance design seals harder as boost rises, and the billet body won't crack or leak like the plastic OEM valve.
What's it made of?
Billet aluminum with high-temperature O-rings and an integrated high-temp solenoid.
