You need to build a kit with pipes and bends to fit your car. It's also important to shield the filter from the engine heat and let it suck fresh cold air, or you will decrease your engine performance. **Q: hello , please inform me if this airintak fit mini cooper S 2004 supercharge or no ? thanks** A: Bro I think this air intake fit all cars , but you need to have the right air intake pipe that goes to the trootlebody **Q: how many inch ?** A: It comes with 3 different sizes to fit whatever size you need **Q: Anyone install this filter om a nonk&n intake? new to me truck has what looks to be a cheap 4"old air intake. want to get a better filter for it** A: Yes I installed it on my 2009 Yamaha wave runner.
