JetPrime SLS/AIS Block-Off Plate Kit for Ducati Panigale 959 (2016-2019) – JP ES 005

If you have fitted an aftermarket exhaust to your Ducati Panigale 959, the factory PAIR (Secondary Air Injection) system becomes a liability rather than an asset — introducing popping, backfiring and a ragged throttle response that undermines the benefits of your new pipe. The JetPrime JP ES 005 SLS/AIS block-off plate kit is the straightforward, well-engineered solution: a CNC-machined 7075 aluminium plate replaces the original cover and rubber cap, sealing the airbox port cleanly and allowing you to remove the entire PAIR system for good.

Key Features

• Eliminates exhaust popping and backfiring that commonly occur when running aftermarket exhaust systems on the Panigale 959
• Enables a true, stable air/fuel ratio for reliable and precise fuel mapping
• Improves throttle response and fuelling consistency with aftermarket exhausts fitted
• Allows complete removal of the PAIR system including the valve, cover and hoses
• CNC-machined from 7075 aluminium for maximum precision and durability
• Includes heat-resistant rubber caps engineered for long service life under high thermal loads

How It Works

The PAIR system was designed by Ducati to reduce emissions on the standard exhaust. When a freer-flowing aftermarket system is installed, secondary air drawn back through the PAIR circuit reacts with unburnt gases in the exhaust, creating the characteristic popping and erratic fuelling that riders find so frustrating. The JP ES 005 kit plugs this circuit permanently. With the block-off plate in place and the PAIR components removed, your ECU and any fitted power commander or quickshifter can work with clean, consistent airflow data — the foundation of a properly sorted tune.

Build Quality

JetPrime developed and tested this kit specifically for the Panigale 959, so fitment is exact rather than approximate. The block-off plate is machined from 7075-series aluminium — a high-strength aerospace-grade alloy — giving it the rigidity to maintain a lasting seal without distortion. The accompanying heat-resistant rubber caps are rated for the thermal environment of a working exhaust bay, so longevity is not a concern even during extended track sessions.

Practical Value

For track-day riders and club racers, this is one of the highest-return, lowest-cost modifications available for the 959. The installation is straightforward, the components are durable, and the improvement in fuelling behaviour is immediately noticeable. Rather than chasing mapping solutions around a system that was never designed for aftermarket exhaust use, the JP ES 005 simply removes the source of the problem.
