Replacement Air Filters
Your intake is only as good as the filter in it. A loaded filter chokes airflow, and on a diesel that shows up as sluggish throttle and rising EGTs long before you see a check-engine light.
These are direct replacement filters for cold air intake systems — oiled cotton gauze and dry synthetic media, both washable and reusable for the life of the vehicle. Replace on a schedule if you run dusty two-tracks or wash-boarded forest road; a filter is cheap, a turbo is not.
Choosing the right replacement filter
Filters are matched to the intake kit, not to the vehicle — two trucks with the same engine can take different filters depending on which intake is installed. Check the part number on your existing filter or the kit number on your intake lid before ordering.
Oiled vs. dry media
Oiled cotton traps finer dust and is the traditional choice for heavy off-road use. Dry media cleans up with soap and water and skips the re-oiling step, which matters if you are running a MAF-equipped gas engine and want to avoid over-oiling.
Replacement Air Filters FAQs
How do I know which replacement filter fits my intake?
Find the part number of your cold air intake kit, then look for it in the filter title. Many listings say which kit they fit, such as a screw-in or snap-in lid intake. If you cannot find the number, call (920) 249-7744.
Will an S&B filter fit a different brand of intake?
Only if it is a flange-style or universal filter whose dimensions match. Read the flange diameter and element length rather than assuming it matches.
What is the difference between a dry and a cotton filter?
A dry filter uses synthetic media with no oil, while an oiled cotton gauze filter is treated with filter oil. Both can be cleaned and reused, and each has its own cleaning procedure.
How often should I replace or clean an air filter?
It depends on conditions. Dusty trails and gravel roads load a filter faster than highway driving, so check it more often in those conditions and follow the manufacturer's schedule.
Can I use an aftermarket filter in a stock airbox?
Only if it is made for that airbox. These listings are replacements for intake kits, so check that yours is an S&B or JLT system.
