C&L Performance
C&L offers a sweet cold-air intake kit for '05-and-newer Mustangs. The Trueflow Air Intake system comes complete with a cone air filter, a slick-looking inlet tube, and all of the necessary equipment to hook it up. With one of its cold-air kits installed, C&L expects you to pick up around 16 hp. Of note is how the kit is sold. You can either purchase it alone for $299 or with a Predator tuner for $649.
Diablosport
The same Predator tuner offered in the C&L Trueflow Air Intake system can also be purchased separately from DiabloSport. It comes with a program ready to be flashed onto the ECM of your Mustang. The provided tune optimizes spark timing, air/fuel ratio curves, and automatic transmission shift points and firmness. It is available for V-6 cars of all years. Call DiabloSport for pricing.
Hawk Performance
Going fast is awesome, but being able to haul down the ponies afterwards is just as cool. Thanks to Hawk Performance, the stopping part is a bit easier with its ceramic-coated front brake pads. The pads fit '99-'04 Mustangs, and are at home on both the street and on the track. Even though those in the Mustang community go after the GM guys all the time, it can't hurt to tell you these are the same pads used in the C5 Corvettes. Retailing for $79.99, the pads are a simple and cheap way to improve the stopping power of your boulevard bruiser.
JLT Performance
JLT Performance offers a cold-air induction system for the '05-and-up V-6-equipped Mustang. Based off the company's GT system, the induction kit consists of a CNC'd billet MAF housing and an SCT tune that will improve the power output of the 4.0 six-banger by 10-14 hp. Looks are not forgotten, as the kit can be color-matched to your Stang's exterior. The standard kit costs $555, with the color-matched kit coming in at $570.
Mustang Tuning
Mustang Tuning has a ton of speed parts for the V-6 cars, but there were two items that caught our attention. First is its cold-air kit, which includes a high-flow air filter, a MAF adapter, and all the accessories needed to install it on your Mustang in no time flat. The kit fits all '99-'03 3.8L Stangs, and will set you back $74.99. Next up is the Superchips XCalibrator 2 Tuner. This is the advanced version of the SCT XCalibrator, and has more tools than the original. The tuner can be programmed to work with an OBD-II Mustang from 1996 to 2005-and-up, and allows you to play with the tune of your car for maximum performance. The tuner retails for $379.99.
Mustang Racing Technologies
Mustang Racing Technologies (MRT) showcased the possibilities of V-6 performance with its blown, V-6-equipped '05 drop-top Mustang. Since then, MRT has developed many different types of go-fast goodies for the six-cylinder group. Its cold-air kit is a direct bolt-in and features a redesigned air intake tube for better flow and less turbulence. The kit also features a new mass airflow sensor housing, a high-flow K&N filter, and a plenum dressed in carbon fiber. It retails for $318.95, but tack on an extra $38 for the K&N filter. Getting air in to make power is important, but getting it out quickly is also key. To that end, MRT has the V-6 cars covered with the AeroTurbine axle-back exhaust system. The system is made of lightweight stainless steel and comes with 311/42-inch chrome exhaust tips welded on. It will make your little six-banger sound mean while freeing up some ponies. The exhaust system is priced at $225.
