Clamp On Air Filter

The K&N Engineering Clamp On Air Filter (model RU-1710) is engineered for builders and mechanics who demand maximum engine breathing without permanent modification to factory intake systems. This universal clamp-on design solves a critical problem: upgrading airflow on vehicles where traditional drop-in or bolt-on filters don't fit or where intake ducting requires flexibility. Whether you're tuning a custom engine, retrofitting an unconventional intake manifold, or working with limited clearance, this filter offers the performance benefits of premium filtration with installation simplicity that respects your original hardware.

K&N's washable, reusable cotton-gauze media design dramatically outperforms paper filters in both airflow and service life, allowing you to maintain peak engine efficiency across thousands of miles. The clamp-on mounting system uses a 4.625-inch inlet diameter with a robust rubberized connection point that seals cleanly against intake tubing, eliminating air leaks that rob horsepower and throttle response. The compact 7.25-inch height and lightweight 0.71-pound construction make this filter ideal for tight engine bays where space is precious, while the high-flow architecture reduces intake restriction—critical for naturally aspirated engines seeking every fractional gain in volumetric efficiency and fuel atomization.

This filter suits custom fabricators, performance shops, and enthusiasts building non-standard intake systems where universal fitment is mandatory. Installation requires only a hose clamp and basic hand tools—no cutting, drilling, or welding. The reusable media design also appeals to budget-conscious builders planning long-term ownership, since K&N filters can be cleaned and re-oiled using the manufacturer's service kit rather than replaced. Verify your intake tube diameter matches the 4.625-inch inlet before purchase; this universal clamp-on excels on turbocharged builds, supercharged conversions, and carbureted restorations where intake architecture breaks from OEM convention.
