PREracing Anti-Stumble Kit - Fits 08-21 Subaru STI

Was very skeptical of this product and no UK reseller I bit the bullet and ordered from PRE racing, this came exceptionally quick and was fitted just as quick, my stumble is all but gone low speed driving is so much better now not sitting there at 2-3k with the car just not knowing what is going on it's way smoother now no jerky feeling Great buy!

Life saver without breaking the bank

I have a 2018 STi with a stage 2 tune/bolt on mods. The stumble at certain RPM was definitely real and not a myth. This kit saved the joy of driving, much smoother experience, and awesome pricing for its engineering worth. Thank you PRE-Racing!

Fast shipping can't wait to install it.
