Description
xUpgrade overview
Meet the Suspenix Aluminum Oil Filter Cap, a robust upgrade designed to replace a stock plastic cap on 3.6L Jeep powertrains. Built for regular oil service, this cap aims to deliver a smoother removal process and a durable seal during changes. The aluminum construction provides a resilient alternative to brittle plastic, and the included O-ring helps maintain a clean seal throughout the service cycle.
The original plastic cap has a known tendency to crack or snap during oil changes, particularly when removing the cartridge. The Suspenix cap uses a solid aluminum housing and an included O-ring to help maintain a reliable seal. This combination can reduce stress on the upper portion of the filter housing during service and offers a longer-lasting alternative when the cap is removed and reinstalled multiple times.
Key benefits and fitment
- Aluminum construction delivers a tougher, longer-lasting cap compared with a plastic stock part.
- Direct replacement that fits the 6-cylinder 3.6L engines in the listed Jeep models.
- Includes replacement O-ring to help ensure a clean seal during oil changes.
- Designed to work across multiple 3.6L platforms beyond Jeep, including other 2014-2020 vehicles listed in the data.
