Machined from aerospace-grade 7075 aluminium and developed specifically for the R6 across its entire 2003–2026 production run, this cover pairs race-ready function with a finish that looks as purposeful as it performs.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003ePermanently eliminates aftermarket exhaust popping and misfires by fully removing the PAIR (Secondary Air Injection) system, including the valve, cover and hoses\u003c\/li\u003e\n\u003cli\u003eSeals the airbox aperture cleanly with a precision CNC-machined 7075 aluminium block-off plate, replacing the factory cover and rubber cap\u003c\/li\u003e\n\u003cli\u003eRestores a reliable, consistent air\/fuel ratio for precise fuelling and sharper throttle response when running aftermarket exhaust systems\u003c\/li\u003e\n\u003cli\u003eHeat-resistant rubber caps ensure long service life and robust performance under sustained track conditions\u003c\/li\u003e\n\u003cli\u003eDesigned, tested and developed exclusively for the Yamaha YZF-R6, guaranteeing exact fitment across all model years from 2003 to 2026\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhy the PAIR System Causes Problems with Aftermarket Exhausts\u003c\/h2\u003e\u003cp\u003eThe Secondary Air Injection system — known on Yamaha as PAIR — channels fresh air from the airbox into the exhaust tract to help combust unburned fuel. On a standard exhaust it reduces tailpipe emissions, but once an aftermarket system is installed the altered exhaust gas dynamics interact with that secondary airflow to produce the characteristic popping, backfiring and hesitation that frustrate riders on track. The JetPrime JP ES 033 removes the system entirely, closing off the airbox port and allowing the engine management to work cleanly with the altered exhaust, delivering a crisper throttle response and more predictable fuelling throughout the rev range.\u003c\/p\u003e\u003ch2\u003eConstruction and Finish\u003c\/h2\u003e\u003cp\u003eJetPrime's reputation is built on uncompromising manufacture, and the JP ES 033 reflects that heritage in every detail. The block-off plate is machined from 7075-series aluminium — the same alloy used in aerospace and high-load racing components — rather than the softer 6061 grade common in budget alternatives. The result is a cover that withstands heat cycles, vibration and the mechanical stress of sustained track use without distortion. Complementary heat-resistant rubber caps complete the kit, ensuring every port in the system is sealed correctly for lasting reliability.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThe JetPrime JP ES 033 is designed exclusively for the following model:\u003c\/p\u003e\u003cul\u003e\u003cli\u003eYamaha YZF-R6 — all variants, model years 2003 to 2026\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003ePlease note: this product is for race use only and is not approved for use on public roads.\u003c\/p\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eBrand: JetPrime\u003c\/li\u003e\n\u003cli\u003ePart number: JP ES 033\u003c\/li\u003e\n\u003cli\u003eMaterial: CNC-machined 7075 aluminium block-off plate with heat-resistant rubber caps\u003c\/li\u003e\n\u003cli\u003eFunction: SLS \/ AIS (PAIR) system block-off cover\u003c\/li\u003e\n\u003cli\u003eFitment: Yamaha YZF-R6 (2003–2026)\u003c\/li\u003e\n\u003cli\u003eIntended use: Track \/ race use only — not road legal\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"JetPrime","offers":[{"title":"Default Title","offer_id":53168766288138,"sku":"JP ES 033","price":78.68,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/JP_ES_033_277b8474-e388-419d-9a95-432626ee80cc.png?v=1780814164","url":"https:\/\/inter-pace.com\/products\/jetprime-sls-ais-block-off-cover-yamaha-yzf-r6","provider":"Inter-Pace","version":"1.0","type":"link"}
