The K&N RE-0950 is a round tapered universal clamp-on air filter with a rubber top, a 6-inch base, a 4-5/8-inch top, and a 6-inch height. Its 3.5-inch flange inside diameter is the dimension to verify against your intake tube before ordering. The manufacturer rates overall filter efficiency at up to 99%, and the filter has a red finish and a 1-year limited warranty.
Compared with a disposable paper element, the case for this filter is reuse. The manufacturer lists a 1.27 oz re-oiling amount, and K&N's install sheets for its reusable filters point owners toward periodic inspection and cleaning instead of replacement. Over several service cycles, one cleaned and re-oiled element can offset a higher up-front price. Because it is a universal design, fitment depends on matching dimensions rather than looking up a model year. Owners on user forums suggest fully loosening the clamp, warming the rubber lip with a heat gun, and using a light lubricant such as WD-40 to slide the flange into a tight airbox. Those same owners warn that oil reaching a mass airflow sensor can trigger a check-engine light. Searches for this part often include K&N RE-0950 universal clamp-on filter, 3.5 inch flange universal air filter, and reusable cold air intake filter for custom intake.
No. The manufacturer classifies it as a universal round tapered air filter, so fit depends on whether your intake matches the 3.5-inch flange, 6-inch base, and 4-5/8-inch top dimensions.
K&N's installation sheets for its reusable filters recommend periodic inspection and cleaning, and they point owners to the manufacturer's Recharger service kit for cleaning and re-oiling.
The manufacturer lists a 1-year limited warranty on this filter.
A clamp-on universal filter is a moderate-difficulty job that takes about the same tools as a standard intake swap. You will need a screwdriver or nut driver for the hose clamp, a heat gun or hair dryer, and a light lubricant such as WD-40 or silicone grease. Owners on user forums recommend loosening the clamp completely so it can hang loose while you position the filter, then reattaching and tightening it once the flange is seated. The rubber flange can be stiff in tight airboxes, so warm the lip gently rather than forcing it. Keep lubricant and filter oil away from the mass airflow sensor, and avoid pushing the rubber over sharp edges. K&N's installation sheets for some of its boxed filters call for sealing grease along the seal, so consider a thin bead of grease at the flange contact point if your intake seals poorly.
