Trade the annoying post-intake "thump" for a genuine blow-off valve "Pssshhh" on your Tundra, Sequoia, or Lexus GX 550.
Fixes the Infamous "Thump"
If you've added an intake to your 2022+ Tundra, 2023+ Sequoia, or Lexus GX 550, you've probably heard it — a dull thumping noise every time you lift off the throttle. That's the OEM recirculation valve, now audible because the less-restrictive aftermarket intake lets you hear it open and close.
This insert kit fixes it. When the inserts are installed and the OEM valve opens, that thump is replaced by a classic blow-off valve "Pssshhh" at roughly the same volume — not overwhelming, not flashy. Just the right amount of sound.
✅ Lexus GX 550 Fitment — Verified
We've confirmed this kit fits the 2021+ Lexus GX 550, which shares the twin-turbo V6 platform with the Tundra and Sequoia. GX 550 owners get the same thump-eliminating, blow-off-valve sound upgrade — same bolt-on install, same billet quality.
Built From Billet, Made to Last
Each insert is CNC machined from billet 6061 aluminum, then anodized black and laser-engraved with the SXTH Element logo. It installs between the OEM valve and the cold-side charge pipes and comes with all the hardware you need for a clean bolt-on installation — no cutting, no permanent modifications.
