I don't know if its been done before but a search drew a blank - is a performance air filter such as a K&N or PiperCross worth the outlay? I'm on a 2015 Speed Triple R with Arrow end cans, so wondered if a performance filter would complement the after market exhaust? Anyone using one to their benefit?
Improving the inlet airflow will deliver more power but only if the fuelling map in the ECU is altered to suit.
