The JetPrime JP ES RSV4 SLS\/AIS block-off kit replaces the original PAIR (Secondary Air Injection) valve cover and rubber cap with a precision CNC-machined plate, sealing the airbox cleanly and restoring a consistent, accurate air\/fuel ratio across every point of the rev range.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eEliminates exhaust popping and misfires caused by aftermarket slip-on or full-system exhausts — ride cleanly without the drama\u003c\/li\u003e\n\u003cli\u003eRestores a true, reliable air\/fuel ratio for precise fuelling and stable mapping on both road ECU flashes and track-day tune files\u003c\/li\u003e\n\u003cli\u003eImproves throttle response when running full aftermarket exhaust systems by removing the erratic PAIR valve influence\u003c\/li\u003e\n\u003cli\u003eAllows complete removal of the PAIR system — valve, cover and all associated hoses — for a tidier, lighter engine bay\u003c\/li\u003e\n\u003cli\u003eCNC-machined from 7075-series aluminium for maximum rigidity, corrosion resistance and an exact fit every time\u003c\/li\u003e\n\u003cli\u003eHeat-resistant rubber caps supplied for long service life under the extreme thermal loads of a high-output V4\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhy the PAIR System Causes Problems with Aftermarket Exhausts\u003c\/h2\u003e\u003cp\u003eThe PAIR system was engineered to reduce emissions on the factory exhaust by injecting secondary air into the exhaust ports. Once an aftermarket system is installed — particularly a full system without a catalytic converter — the PAIR valve introduces unwanted air pulses that upset the exhaust scavenging cycle. The result is audible backfiring on the overrun, stuttering throttle pick-up and a fuelling map that can never be tuned cleanly because the air mass entering the ports is inconsistent. Blocking the system off at the source is the accepted, permanent solution.\u003c\/p\u003e\u003ch2\u003eBuild Quality\u003c\/h2\u003e\u003cp\u003eJetPrime has machined the block-off plate from 7075 aluminium — the same aerospace-grade alloy used in competition components — rather than the softer 6061 found in many budget alternatives. The tighter grain structure resists distortion under heat cycling and maintains the seal integrity that a closed airbox demands. Every dimension is developed specifically for the RSV4 platform; no drilling, no modification, no adapters.\u003c\/p\u003e\u003ch2\u003eTrack Use\u003c\/h2\u003e\u003cp\u003eDeveloped and tested exclusively for circuit use, the JP ES RSV4 kit pairs naturally with any track-day or race preparation of the RSV4 family. Whether you are running a full Akrapovic or Termignoni system on a RSV4 RR cup bike or simply cleaning up a Factory with a slip-on, this block-off plate removes the final variable that prevents a clean dyno pull and a stable fuelling curve.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eDesigned and tested specifically for the following models:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eAprilia RSV4 (2009–2026)\u003c\/li\u003e\n\u003cli\u003eAprilia RSV4 R (2009–2026)\u003c\/li\u003e\n\u003cli\u003eAprilia RSV4 RR (2009–2026)\u003c\/li\u003e\n\u003cli\u003eAprilia RSV4 RF (2009–2026)\u003c\/li\u003e\n\u003cli\u003eAprilia RSV4 1100 (2009–2026)\u003c\/li\u003e\n\u003cli\u003eAprilia RSV4 1100 Factory (2009–2026)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eNote: Race use only.
