Installing A K&N Intake Filter In Your Mustang - 93' LX V8
Since adding K&N's full line of intake products on our store - Click Here For Our Full Selection - we decided to give one of them a try on our 93 LX project car. We opted for a large filter unit that replaces the stock airbox and rubber piping. The install was very straight forward and took only a few hand tools. Install took no more than 45 minutes to complete.
K&N filters are special because of their high flow characteristics and their superior engine protection. By using an oiled element they are able to trap the most dirt and dust compared to a factory paper filter or a standard replacement filter. Not only do they flow and filter better, but they are completely re-usable and will last the life of your vehicle's engine. By using K&N's Filter Recharge Kit you can clean and re-oil your filter back to new. They recommend you clean your filter every 20,000 miles to ensure the best protection and performance. After several years and a hundred thousand miles, the K&N filters practically pay for themselves. You actually CAN save money while gaining performance, reliability & economy...who woulda thought? Now on to the install for foxbody Mustangs:
Next, remove the clamp below the MAF sensor using a flathead screwdriver.
Once the clamp is removed, pull the factory intake assembly out of the engine bay.
Once the airbox is removed, you will need to use your 1/4" drill bit to slightly enlarge a hole for the K&N filter's bracket mounting position.
Once the bracket bolt fits through the hole, fit the bracket in place and tighten it. You will have to reach under the bumper to tighten the nut from the bottom of the bolt.
Once the bracket is in place and is snug, it's time to install the new filter. Get the filter in place and make sure the threads on the end of the filter fit inside the bracket. Tighten the 11mm nut on the end of the filter.
Next tighten the hose clamp at the filter opening to ensure there will be no air leakage.
That's it! You're done! Below are two photos comparing the factory intake and the new K&N filter.
