• Sealed In Silicone: The silicone sealing gasket holds a tight seal in harsh, dusty conditions, so unfiltered air cannot slip past the edge into the intake.
• Installs In 5 To 10 Minutes: A single drop-in panel that seats in the factory airbox with no cutting or tuning. Most drivers swap it in five to ten minutes.
• Know Your Change Interval: Replace every 5,000 to 10,000 miles, or 12,000 miles at the most, and sooner on dusty or unpaved roads. Verified fitment means fewer returns.
