This is the replacement air filter for the STILLEN TruPower cold air intake on GM half-ton trucks. If your intake filter is dirty or you want a fresh one on hand, it restores the airflow the intake was built around. It is a cone-shaped, high-flow filter with a durable, long-life build and a higher dirt-holding capacity, sold individually.
It comes in two media types. The oiled filter is washable and reusable. The dry filter suits owners who want the lower-maintenance option. Either way, a secondary flange seals directly against the airbox housing so unfiltered air does not slip past.
Fitment
The oiled filter (STIL-F86960) matches intake part numbers TP403504 and TP403506. The dry filter (STIL-F86960D) matches TP403505 and TP403507. STILLEN lists these applications, 5.3L and 6.2L engines only: 2019-2026 Chevrolet Silverado 1500, 2017-2026 GMC Sierra 1500, and 2021-2026 Chevrolet Tahoe, Chevrolet Suburban, GMC Yukon and Cadillac Escalade. Not for sale in California.
Install notes
It drops into the matching STILLEN airbox; check the intake part number you own against the fitment above before ordering.
