Machined from aerospace-grade 7075 aluminium and developed with the exacting standards JetPrime applies across its race-focused catalogue, this kit eliminates the Secondary Air Injection (PAIR) system entirely — replacing the factory cover and rubber cap with a clean, purpose-built solution that puts aftermarket exhaust performance where it belongs.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eEliminates exhaust popping and misfires that arise when aftermarket exhaust systems are fitted to the Yamaha YZF-R3\u003c\/li\u003e\n\u003cli\u003eRemoves the complete PAIR system — valve, cover and hoses — for a cleaner airbox and reliable air\/fuel ratio\u003c\/li\u003e\n\u003cli\u003eCNC-machined block-off plate in 7075 aluminium delivers maximum durability, precise fitment and a finish that reflects JetPrime's heritage in motorsport engineering\u003c\/li\u003e\n\u003cli\u003eHeat-resistant rubber caps ensure longevity and resilience under race-level thermal loads\u003c\/li\u003e\n\u003cli\u003eOptimised throttle response and fuel mapping stability when running full aftermarket exhaust systems\u003c\/li\u003e\n\u003cli\u003eDeveloped and tested exclusively for the Yamaha YZF-R3 (2015-2023) — a direct, no-compromise replacement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eDesign, Finish and Heritage\u003c\/h2\u003e\u003cp\u003eJetPrime has built its reputation supplying riders and race teams who demand components that look as purposeful as they perform. The JP ES 015 block-off plate carries that philosophy through in every detail: the CNC-machined 7075 aluminium face is finished to close tolerances, replacing the factory plastic cover with a component that visually signals the upgrade beneath it. Where the standard Yamaha airbox cover is a functional afterthought, the JetPrime plate is a considered piece of hardware — compact, precise and engineered to last across many track seasons.\u003c\/p\u003e\u003ch2\u003eHow the PAIR System Affects Your Aftermarket Exhaust\u003c\/h2\u003e\u003cp\u003eThe Secondary Air Injection (PAIR) system — sometimes called SLS or AIS — feeds fresh air from the airbox into the exhaust stream to help combust residual fuel and reduce emissions in stock trim. It is optimised for the factory exhaust and its specific back-pressure characteristics. Fit an aftermarket slip-on or full system and the dynamics change: the PAIR valve introduces air at the wrong moment, causing the characteristic popping and backfiring on deceleration and disrupting the air\/fuel ratio your fuel injection relies on for clean mapping. Removing the system completely, as the JP ES 015 kit allows, restores a stable, consistent A\/F ratio and gives your ECU or Power Commander the clean baseline it needs.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eThis kit is designed and tested for the following fitment:\u003c\/p\u003e\u003cul\u003e\u003cli\u003eYamaha YZF-R3 — model years 2015, 2016, 2017, 2018, 2019, 2020, 2021, 2022, 2023\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003eRace Use Only.
