WE RECOMMEND YOU HAVE YOUR TUNE CHECKED ANYTIME YOU MAKE A PART CHANGE ON A SUPERCHARGED CAR! AIR FILTER OPTIONS – OIL OR DRY We use only the best air filters made by S&B to our specifications. For years we only used oiled filters, but dry filter technology has been proven and is now a popular option. Should I choose a Dry Disposable or Cotton Oiled Filter? Since you are not sacrificing performance with either choice, the decision comes down to would you rather throw away the filter or clean it. Dry: Comparable airflow to oiled cotton filters with the same great protection. Last for up to 30,000 miles of highway driving. Extend the life of the filter using compressed air. Oil: Oiled filters can last forever as long as you properly clean and re-oil it. See picture of filters below. Oil filters are available in red or blue and Dry filters are white. MAINTENANCE To properly clean your oil filter, we recommend the S&B Precision II Cleaning & Oiling Kit. *TIP* by purchasing a 2nd air filter you can simply swap filters when it’s time to clean it and not be rushed. Clean the first filter and it’s ready when it’s time to change again. JLT Pre-Filters are now available for most intake kits we carry, these filters are made for us by Outerwears, these prefilters are water repellent. They will increase your filter life and cut down on your cleaning intervals!
