In 2002, Ford completely redesigned the mass air flow unit for the Mustang. The new unit continued to measure in at 80mm, but with an integrated air temperature sensor and different flow characteristics. Through dyno testing and the development of an all-new replacement MAF housing, C&L is now able to introduce a new MAF package for 2002+ Mustang GT vehicles. Similar to our popular kits for the 1996-2001 Mustangs, our new kit #10699A comes complete with a new 85mm MAF housing, K&N air filter assembly and plastic shield to hold the assembly in place and draw cold air in from the fender.

Dyno testing has shown this package to consistently deliver an average increase of 9 HP from 3000 RPM to redline with an average torque gain of 9, and a peak horsepower gain of as much as 14 between 5500-5700 RPM. The 85mm unit used in this package cannot be used with earlier model vehicles. Due to the fact that the new sensor uses a different style electronics module, larger than stock injector sizes must be accommodated through a computer upgrade in the same manner that all supercharger systems utilize for 1999 and new GT Mustangs.

Installation takes approximately 10 minutes. Here's how: Take off the stock air box and the hose clamps securing the mass air meter. The electronics are unbolted from the factory plastic mass air meter and installed on the C&L meter. The new meter is clamped to the stock rubber inlet tube. Install the new air filter cover and you're done.

C&L now offers a complete air system that replaces the factory air assembly, while still retaining the factory Mass Airflow assembly (MAF). It has fast become our most popular selling product.

This system features the exclusive "TrueFlow" intake pipe, unlike other designs that have proven to restrict airflow and hinder system performance.

Our Mustang Dyno-testing and development has proven this system to be the "must have" item for those looking to maximize the performance on naturally aspirated 4.6L Mustang applications. As an added bonus, Dyno-testing has shown a typical power gain of 10+ rear wheel horsepower and 14 ft/lbs of torque over the stock air assembly.

Installation time is less than 20 minutes, tools required; a flat head screwdriver, a ¼ drive socket wrench with a ¼ socket.

C&L TrueFlow Filter Systems are designed for those who are looking for a complete low cost replacement for the poor flowing original factory air box used on all 1996-2004 Ford Mustang GT, Cobra vehicles. These kits are "meter forward" packages for those people who are not interested in upgrading the mass airflow unit at this time, yet still want the flexibility to upgrade their inlet pipe and mass airflow units as they see fit.

Each system comes complete with a mass airflow filter adapter, adapter hardware, conical high performance air filter and specific molded filter cover for each vehicle application.

Installation of this kit is quite simple and should take no more than 15 minutes to complete. For installation, you will need; a flat head screwdriver, a ¼ drive socket wrench with a ¼ socket and a small adjustable wrench.

TrueFlow inlet pipes are now available separately for most popular V8 Mustang applications. These inlet assemblies offer three key features which have made them a very popular bolt-on for use with a wide variety of air meters. The cast aluminum finish with blue silicone hoses really dress up the engine compartment and are much more attractive than the factory black rubber assembly. Due to the fact that these pipes are cast, the inside diameter is consistent all the way through the pipe from the air meter to the throttle body and this is what gives it the name "TrueFlow". By eliminating the flexible ridges in the factory rubber inlet tubes and by controlling the inside diameter for consistency, a modest horsepower gain is achieved.

Most vehicles will receive approximately 3 rear wheel horsepower, however several tests have been reported to show as much as 5 horsepower on some applications. For those who are interested in running nitrous oxide, we have cast a special nitrous boss into each TrueFlow inlet pipe to give you a solid location in which to drill and tap your nozzle. Due to the fact that these pipes are solid aluminum and are mounted directly to the engine, we do not recommend mounting the mass air flow unit (through a bracket) to the body of the vehicle. When using an aftermarket intake that relocates the throttle body away from the stock position, it may be necessary to make minor modifications for proper fit.

TrueFlow inlet pipes are currently available for the following applications, with others in development for future release.

Installation of this kit is quite simple and should take no more than 20 minutes to complete. For instillation, you will need; a flat head screwdriver.
