Before installing this product, read these instructions paying special attention to the section in red.
Note: Due to the nature of the computer processor, a computer re-tune is necessary when installing this air intake assembly. We offer an optional 50 state legal "no-tune" calibration insert for this system which does not require a tune. Please contact us for this item if you do not want to re-program the processor.
The C&L 7140 Predator tuners come with dyno developed tunes programmed for our system. It is accessible from the main "Performance" menu, and your computer is automatically loaded with the appropriate adjustments when selected. If your C&L kit came with a Predator Tuner and the C&L logo does not come up when you install the tuner, you must obtain your CAL ID and acquire a custom tune from the business you purchased the kit from or you may purchase a tune from C&L.
If you are not using a Predator to adjust the computer for this system, it is strongly recommended that you have your vehicle dyno tuned in person by a knowledgeable tuner using a wide-band air/fuel ratio monitor or use our optional "no-tune" calibration insert. A "mail order" program is not recommended. If you install this system prior to having the computer re-tuned, do not run the vehicle under a heavy load or at wide-open throttle until the computer adjustments have been made.
The Predator performance tune programmed for our system may be altered if you make any changes that may affect the air/fuel ratio. Installing a "Cat-Back" exhaust will not require any adjustments, but the installation of an "off road" or high-flow catalytic "X" or "IT pipe, headers or a throttle body may require you to add fuel at wide open throttle. The use of a dyno equipped with a wide-band air/fuel ratio monitor is vital to make such adjustments, and you should try to maintain your wide open throttle air/fuel ratio from 12.8:1 (conservative) to 13.2:1 (aggressive) in the upper RPMs.
Tools needed for installation: a flat blade screwdriver, socket wrench with extension, 8mm socket, 10mm socket and a socket driver for the supplied 1-20 torx bit. Important note: all Mustangs built after December 2005 use self-tapping screws to hold the MAF sensor in place. DO NOT USE THE SELF-TAPPING SCREWS IN OUR MAF HOUSING. In your bracket and bolt package supplied with this kit, we have provided new MAF sensor screws to replace the factory self-tapping screws. If you use the factory screws, you will risk damaging your new housing.
Installation of this system is relatively simple, and should be accomplished within a short period of time. A small change in how the hose clamps on to the pipe can effect fitter location and filter shroud fit. When installed properly, the mass airflow housing and air filter neck w ill pass through the round cut-out on the filter shroud.

To remove the stock assembly, loosen the clamp that secures the stock inlet hose to the throttle body. Next, you will notice a nylon vacuum hose that runs from the valve cover to the left hand side of the stock inlet pipe. Reach under the fitting that attaches this hose to the inlet pipe, and you will find that there is a little green tab that is pointing straight down. Pull this tab towards the rear of the vehicle and then pull the connector towards the passenger side of the vehicle. The green tab will now clear the catch that is located on the stock vacuum nipple fitting on the inlet pipe. Next, you will disconnect the MAF sensor located on the front of the air filter housing which has a wiring connector plugged into it. To disconnect, slide the red tab on the connector towards the front of the vehicle. This will unlock the connector; slide the connector off the MAF sensor by squeezing the tab and pulling it towards the front of the vehicle. Goto the end of the air filter assembly, and you will see a 10mm bolt located between the driver's side fender and the air box. Loosen and remove this bolt and set it aside for future use. Using a pair of large pliers, squeeze the spring clamp that is located on the middle of the back side of the factory inlet tube. This is the "noise transmission tube" which delivers engine sounds to the passenger cabin. While the spring clamp is fully squeezed, simply pull the plastic round noise tube away from the factory rubber inlet pipe by pulling it towards the rear of the engine compartment, away from the inlet tube. You must now separate the mass airflow wiring harness from the factory air filter box assembly. There is
