RallySport Direct is proud to carry high-performance turbocharger components and accessories brought to you by Turbosmart.
Here, you are looking at the Turbosmart BOV Block-Off Cap. This particular cap has been designed to block off the blow-off valve provision on your turbocharger to allow you to add an aftermarket blow-off valve on your intercooler piping.
DETAILS:
- Works with Borg-Warner EFR, Ecoboost, and KKK turbochargers
- Durable billet aluminum construction
- Designed to allow for an external BOV
- Covers the existing blow-off valve provision on your turbocharger
- Includes new O-ring
WHY WE CARRY THIS ▾
We only list parts we’d run ourselves or recommend to a friend building a real car. If it feels vague, unverified, or inconsistent, it doesn’t make the cut.
- Fitment-first mindset — no “universal” roulette
- Brand reputation matters — we favor proven manufacturing
- Support that actually responds with real answers
WHAT TO EXPECT ▾
This is the clean path: correct fitment, clean install, and results that match the intent.
- Install-ready experience with correct mounting where provided
- Finish that holds up to real driving, not just photos
- Selections on this page drive the exact fitment shipped
TRUST, BUILT INTO THE PROCESS.
Anyone can list parts. We curate what belongs on a serious build. Our goal is simple: fewer surprises, cleaner installs, and confidence when you hit “Buy.”
Fitment checked
We prioritize vehicle-specific listings and clear selection logic so you’re not gambling on compatibility.
Brand discipline
Proven manufacturing and consistent quality matter more than hype. We bias toward what actually holds up.
Real support
If you have a question, you’ll get a human answer that helps you finish the build — not a copy-paste shrug.
