You can choose between a cleanable/re - useable form or a classic dry - replaceable form. The cleanable filter is perfect for city and highway drivers who stay off dusty roads. It lasts a long time and can be cleaned with the S&B Cleaning Kit. On the other hand, the dry filter is ideal for trucks used in dusty environments. Once it's used up, just dispose of it. With this filter, your engine can breathe clearly and reach the horsepower you expect. Part Number: CR - 91035. Features include an oiled/dry filter type, a cotton filter that's either cleanable or dry, a cotton gause filter material, red/white filter color, and an 8 - ply rating.

Using this S&B air filter is easy. First, make sure your engine is off. Then, locate the old air filter and carefully remove it. Place the new S&B filter in the same spot where the old one was. If you've chosen the cleanable filter, when it gets dirty, use the S&B Cleaning Kit to clean it. Make sure to follow the instructions on the kit. For the dry filter, once it's too dirty to work well, simply throw it away and replace it with a new one. When driving on dusty roads, check the filter more often. Keep your filter in a dry place when not in use to avoid damage.
