Exclusively available to mountune Online customers is this Cold Air Induction System (CAIS) for the mk6 Fiesta ST.
Based on the cold air package used in the highly successful mountune Fiesta ST MP165 and MP185 performance upgrades, this CAIS features a dual cold air feed to a semi-sealed airbox, custom designed by mountune.
The existing cold air feed is utilised, along with a new dedicated cold air feed from the front grill, that draws cold air into the bottom of the air filter. This ensures this CAIS draws maximum cold air, rather than warm air from within the engine bay.
Removing the extensive restriction of the standard airbox, and replacing it with a well designed high-flow variant, means guaranteed performance increases, as well as a much sportier induction note.
A trade-up value of £175 will be deducted from any future MP165 or MP185 mountune full kit upgrades, providing the car is brought to mountune HQ to ensure correct installation of the CAIS, prior to the core upgrade being fitted.
Easy to fit, and make awesome noise. When I've installed it, the car has only the flexypipe milltek. But now it's good ! Less noise under 1000 rpm More noise over 3500 rpm More torquey at 5000 rpm More noisy like rally car. Smooth acceleration It's really great because it's not too noisy, just what it need. Nice product installed on a french ST150
Just got it installed. Added some bitumen matting on the inside to make it little quiter. On cruising speeds the sound in no different than a k&n panel filter in the original setup, but once you put your foot down it makes a nice crowl. And the engine reacts much better than before. Even idle came down a bit. I love it. Thanks for a great product. Ps: some installation parts were little different than in the installation pdf, but i figured it out.
