JetPrime SLS/AIS Block-Off Plate Kawasaki ZX-10R/RR (2011-2026) JP ES 033

Engineered by JetPrime specifically for the Kawasaki ZX-10R and ZX-10RR across every generation from 2011 to 2026, the JP ES 033 block-off plate is the definitive solution for riders who have already committed to an aftermarket exhaust system. Precision CNC-machined from 7075 aluminium and finished to a standard that reflects JetPrime's Italian race-shop heritage, this cover replaces the factory PAIR valve assembly and airbox rubber cap to permanently seal the secondary air injection port and deliver the clean, responsive fuelling character the ZX-10R deserves.

Key Features

• Eliminates exhaust popping, backfiring and deceleration snatch caused by the PAIR system interacting with aftermarket exhaust systems
• Achieves a reliable, stable air/fuel ratio that supports precise fuel mapping and consistent throttle response
• Allows complete removal of the PAIR system — valve, cover and hoses — for a cleaner airbox bay and reduced weight
• CNC-machined from high-strength 7075 aluminium for maximum durability, precise fitment and a premium finish
• Supplied with heat-resistant rubber caps rated for extreme operating conditions and long service life
• Developed and tested exclusively for the Kawasaki ZX-10R/RR (2011-2026), ensuring a direct OEM-replacement fit

Why the PAIR System Causes Problems with Aftermarket Exhausts

The PAIR (Pulse Secondary Air Injection) system draws fresh air from the airbox into the exhaust ports to assist combustion of residual unburnt fuel and reduce emissions under stock conditions. It was calibrated to work alongside the factory exhaust back-pressure curve. Once an aftermarket slip-on silencer or full exhaust system is fitted, that calibration is lost — the result is unwanted popping on overrun, erratic fuelling, and a fuelling map that fights against any aftermarket ECU or power commander tune. Removing the PAIR system entirely is the accepted track-day and race solution, and the JP ES 033 makes that process straightforward and permanent.

Build Quality and Finish

JetPrime has built its reputation on producing components that look as purposeful as they perform. The JP ES 033 block-off plate is CNC-machined from aerospace-grade 7075 aluminium — a alloy chosen for its superior strength-to-weight ratio over the more common 6061 grade — and machined to tolerances that guarantee a flush, rattle-free seal against the airbox housing. The included heat-resistant rubber caps complete the installation and are designed to withstand the thermal cycling typical of sustained track use. Every dimension is drawn directly from ZX-10R/RR production data, so there is no cutting, grinding or adaptation required.

Track Performance Gains

With the PAIR valve and associated hoses removed and the airbox port sealed by the JP ES 033, the engine management system receives a consistent, uninterrupted air signal. This translates into a more reliable air/fuel ratio, a fuelling map that responds accurately to tuning inputs, and noticeably sharper throttle response when rolling on out of slow corners. For riders running a dedicated race ECU or quick-shifter system, eliminating the PAIR variable removes one further source of fuelling inconsistency — a worthwhile gain at any level of competition.

Fitment and Compatibility

This block-off plate is designed as a direct, no-modification replacement for the factory PAIR valve cover and airbox rubber cap on the following models:

• Kawasaki ZX-10R — all variants, 2011 to 2026
• Kawasaki ZX-10RR — all variants, 2011 to 2026
