OEM Aprilia 90mm Front Stacks for '11-'19 Tuono V4 (AF1-858879)

OEM Aprilia 90mm Front Stacks for '11-'19 Tuono V4

OEM Aprilia 90mm Front Stacks for '11-'19 Tuono V4 (all variants)

Starting with the '17 Model year, Aprilia's RSV4 began utilizing significantly asymmetric velocity stacks to improve mid and upper mid range power with no loss of low end grunt. That got us to thinking of what might happen if you ran a set of shorter stacks on the front cylinders on the Tuono V4 and Tuono V4 1100.  

Sourced from the '09-'15 RSV4-R spare parts catalog, these shorter front stacks typically give a Tuono V4 3-4 more mid and upper mid range horsepower with crisper throttle response and no power loss at low rpm. Peak power is unaffected. 

If you're already replacing the air filter or doing a valve adjustment, these stacks are a cheap and easy performance mod that requires no ecu changes
