JetPrime SLS/AIS closure cap for Aprilia RSV4/1100 Factory/R/RR/RF (2009-2026)
Replace the intrusive secondary air injection system (PAIR) of your Aprilia RSV4 or RSV4 1100 Factory/R/RR/RF (09-26) with the high-quality SLS/AIS closure cap from JetPrime. The JP ES RSV4 kit includes a CNC-machined block-off plate that replaces the original cap and rubber cover to securely seal the hole in the airbox and optimize your bike's performance. The closure cap prevents backfiring and misfires that can occur when using aftermarket exhaust systems.
The PAIR system was originally designed to reduce emissions from stock exhaust systems, but it leads to unwanted noises and misfires when aftermarket exhausts are installed. With this kit, you can completely remove the PAIR system, including the valve, cover, and hoses. This ensures an optimized A/F ratio (air-fuel ratio), improved throttle response, and reliable fuel tuning.
Key features of the SLS/AIS closure cap:
- Prevents backfiring and misfires when using aftermarket exhaust systems
- Achieves a true A/F ratio for reliable and precise fuel tuning
- Improved throttle response when using complete aftermarket exhaust systems
- Complete removal of the PAIR system including valve, cover, and hoses
- Optimizes engine performance and ensures clean tuning
