We stock several replacement and performance drop-in air filters for your BMW. Replacing your intake filter (or filters, depending on vehicle) can improve your BMW's performance immediately.
RK Tunes' intakes increase to 3.5" inner diameter which is much larger than all other front mount intakes for the G80 Platform. Most front mounts neck down to 3” outer diameter through the frame rail area going to the front of the car. Others are reducing from 3.5" to 3.0" to allow the aluminum tubing to fit through. Due to our intakes being silicone, we can have a much larger inner diameter and still be flexible enough to easily install. Having the largest intakes equals the most airflow and the most noise! These also fit the new G87 M2! This is hands down the best design on the market. Designed in-house utilizing high-quality 5-ply wire-reinforced silicone that can never suck shut.
