Give your engine a breath of fresh air with this Rtunes Racing universal air filter. It's a 6-inch tall cone filter with a 102mm (about 4-inch) inlet, designed to replace your stock airbox for better airflow and a bit more horsepower and throttle response. The filter is made with two layers of mesh material and has a strong, pliable rubber flange that absorbs vibration and creates a tight seal – plus it can stretch a little to fit in-between sizes. It's completely washable and reusable, so you can clean it and pop it back on instead of buying new ones all the time. Comes with a stainless steel clamp for secure attachment. Installation is straightforward; just clamp it onto your intake pipe. Perfect for trucks, cars, or performance builds where you want a simple, affordable upgrade. Keep your engine breathing cleanly and add a sporty red touch under the hood.
