Built from high-quality aluminum, this recirculating valve redirects back-flowing charged air into the turbo inlet rather than venting to the atmosphere, helping to prevent compressor stall and delivering a more consistent, responsive boost curve. It’s a smart, cost-effective alternative to OEM plastic valves, offering improved durability and performance under real-world driving conditions.\u003c\/p\u003e \u003cp\u003eDesigned to replace the factory diverter valve on 1.8T and 2.7T engines, it supports a wide range of models including VW Golf\/Jetta\/Beetle and various Audi platforms. The kit is tested for quality and performance, ensuring a smoother boost response with less lag. Note that vehicle compatibility charts are for reference only—always check your OEM part to match your needs. IMPORTANT: Requires 2 sets of these valves for use on 2.7L bi-turbo models. All electronic and mechanical equipment, devices and machines sold by InterCyprus to EU countries are CE certified and carry a two year warranty. At intercyprus.com since 2002 — trusted for quality and reliability.\u003c\/p\u003e \u003cp\u003eThis valve uses a selectable spring system to tune boost release behavior: red spring 8–22 PSI, silver spring 22–30 PSI, and yellow spring 30+ PSI, with a rebuilt kit included for long-term reliability and performance tuning. Reducing boost spiking and maintaining steady turbo operation, it’s suitable for both daily driving and spirited sessions on the track or back roads.\u003c\/p\u003e \u003cp\u003eIdeal for enthusiasts who want a durable, performance-oriented recirculation option that’s easier to install and cheaper than many OEM alternatives. It’s especially beneficial for late-model 1.8T and 2.7T setups where reliable boost control and turbo protection matter most.\u003c\/p\u003e \u003ch3\u003eBenefits \u0026amp; Tips\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003eImprove throttle response and turbo efficiency by recirculating boosted air back into the intake, reducing lag and maintaining consistent boost under load.\u003c\/li\u003e \u003cli\u003eUse the spring selection to match your driving style: red (daily driving), silver (moderate boost), or yellow (higher boost) for specific performance goals.\u003c\/li\u003e \u003cli\u003eFor 2.7L bi-turbo vehicles, remember you may need two valve sets for proper calibration and performance across the system.\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003eProduct Specifications\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003e\n\u003cstrong\u003eBrand Name:\u003c\/strong\u003e PQY\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eModel Number:\u003c\/strong\u003e BOV04\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Aluminum\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Aluminum (as pictured)\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eOEM No.:\u003c\/strong\u003e For 99-05 VW, 98-06 Audi 1.8T 2.7T\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eApplications \/ Compatibility:\u003c\/strong\u003e \u003cul\u003e \u003cli\u003eFor 99-06 Audi TT\u003c\/li\u003e \u003cli\u003eFor 00-06 Audi TT Quattro\u003c\/li\u003e \u003cli\u003eFor 98-05 Audi A4\u003c\/li\u003e \u003cli\u003eFor 98-05 Audi A4 Quattro\u003c\/li\u003e \u003cli\u003eFor 01-05 Audi Allroad Quattro\u003c\/li\u003e \u003cli\u003eFor 00-04 Audi A6 Quattro\u003c\/li\u003e \u003cli\u003eFor 00-02 Audi S4\u003c\/li\u003e \u003cli\u003eFor 99-05 Volkswagen Beetle\u003c\/li\u003e \u003cli\u003eFor 00-05 Volkswagen Golf\u003c\/li\u003e \u003cli\u003eFor 00-05 Volkswagen Jetta\u003c\/li\u003e \u003c\/ul\u003e \u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eSprings Included:\u003c\/strong\u003e Red 8–22 PSI, Silver 22–30 PSI, Yellow 30+ PSI\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e 1x Diverter Valve Kit (100% Brand New Never Used Or Installed); rebuilt kit included\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eQuality \u0026amp; install:\u003c\/strong\u003e 100% quality assurance tested, more responsive, less expensive, easier to install\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003ePackage includes:\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003e1x Diverter Valve Kit.
