The K&N Universal Clamp-On Air Intake Filter (RU-4410) is an excellent addition to my vehicle. It offers a noticeable improvement in airflow, providing a boost in performance. The filter is washable and reusable, which makes it a long-term, cost-effective investment. The fit is perfect with a 3.5-inch flange, and installation was straightforward. Highly recommend for anyone looking to improve engine efficiency and sound!

Filters arrived in great condition. Pleasant surprise that they are pre-oiled. Installed on 1972 MGB/GT.

Flange was smaller than listed. The filter is pretty cheaply made so the fins got bent.

Run one on my Ls swapped S10 and one on my Ls swapped Toyota Hilux. Compact, but breaths enough for a V8.

I have a set of the K&N large filters on my '73 MGB roadster, and while they do a fine job of filtering andflow, they are a major pain to remove and replace for routine carb balancing, etc.These cone shaped ones came recommended from some of my race friends who have used themfor years, and I installed them on my '74 MGB-GT They are a great solution to the problem with the large filters mentioned above.With these cones, I just loosen the band clamp and off they come, for very easy balancing andadjustment, especially helpful when adjusting the mixture on my HIF4 carbs.No issues yet with the actual filtering as well. Highly recommend.

Bought two filters for my 1800 cc MGA engine's twin SU carbs. They fit onto the venturi blocks perfectly and I don't expect any problems. K & N's quality at filtering is well known.Well worth the money.

Very easy to mount on the original (Coopers) RAM-pipes and smart-looking as well. Highly recommended: no more need to renew the filters every 6000 miles or so. K&N's like these last almost forever (just cleaning & oiling every 50.000 miles is enough)
