2006 Ford F250 Super Duty - Super Duper Big

Here is what came in the K&N AirCharger kit: a high-flow cotton gauze filter, a metal heat shield with weatherstripping, plastic inlet tube, and the necessary hardware.

The install process was simple, as well, and started off by inserting the lower bracket to support the inlet tube and bolting on the MAF sensor to the new K&N plastic tube. A nice feature of the kit, K&N included the security-type Allen bit needed to remove the MAF sensor from the factory Ford piece.

Brian then hooked the new K&N inlet tube to the turbo with the supplied rubber mounting hoses and clamps.

Another cool trick, K&N has a provision for the air filter check valve needed to keep things OE.

It was now time to install the heatshield. Notice Brian already placed the weatherstripping on top of the metal shield.

With the inlet tube sticking through the heatshield hole, Brian slid on the high-flow K&N filter and mounted it using the supplied hose and front bracket.

Now ready to let the turbo receive some air, the K&N was done and it was time to move to the MagnaFlow exhaust.

Removing the stock system was as easy as removing the mounts from hangers and unbolting the tubing from the turbo back.

MagnaFlow is well known for many things, including sound and performance, but one thing we love about its kits is the exact fit and zero mounting issues. MagnaFlow included everything needed including high-flow muffler, 4-inch tubing, and 5-inch polished tip.

Bolting on the exhaust was a breeze and only took 15 minutes. We simply slid on the new 4-inch tubing and tightened down the clamps, and it doesn't get much easier than that. The polished muffler is perfect for lifted applications.
