Mustang V6 Performance Parts Guide | 2005-10 4.0L - Mustang V6 Performance Parts Guide | 2005-10 4.0L

The 2005-10 V6 Mustang featured some much needed performance upgrades over the previous OHV 3.8L V6 Stangs; however, Ford still left plenty of room for improvement. Modding your V6 Stang for performance might be laughed at by many Mustang enthusiasts; however, owning and driving a V8-powered Pony car might not be in the cards for every S197 Mustang owner. That is why so many aftermarket companies like LMR have stepped up to provide V6 owners with plenty of performance modifications to help eliminate the performance gaps between the GT models.

There are plenty of YouTube videos and forum posts of very quick 4.0L V6 Mustangs. We have even seen plenty in action at the drag strips and open road course. When starting a performance-based build with V6 Pony Car it is best to start with a plan. You need to decide if you are looking to create a performance Mustang that will be mainly used for street driving, drag use, or open track racing. Having driven a few of these cars and experiencing the “short-comings” in person this is our recommendation for starting a 4.0L Stang project:

Mustang 4.0 Performance Improvements

Air & Fuel | Cold air intake, SCT Tuner, & throttle body

The foundation to any performance build is to help your engine breathe easier. The first step is to add cold air intake. A handheld tuner from SCT and throttle body will help you maximize your air/fuel performance.

Engine | Underdrive Pulley Kit, Coil Pack, & Ignition Wires

An under-drive pulley kit and a performance coil pack will help you get the most performance out of your V6 engine. It is also a good time to upgrade and do some maintenance. Replace spark plugs, plug wires, and fuel filter.

Driveline | Track-lok, rear end gears or 8.8" swap

Installing a higher ratio set of rear end gears such as 3.73 or 4.10 will be one of the most drastic improvements to your acceleration. Due to the lack of 7.5” rear end traction-lok and the high cost of the Auburn limited-slip, many V6 owners opt-in for the 8.8” rear end swap. This swap brings many performance and strength benefits. You will need the SCT tuner to change the gear ratio in your S197 Mustang.

Suspension | Rear control arms & Lowering springs

If you have followed my upgrade plan, you now have increased rear wheel hop due to increased power. Adding a good set of rear lower control arms will help you plant your newly found power to the ground. It is also a good time to get rid of body roll with a set of lowering springs and replace worn out suspension components.

Exhaust| Dual Exhaust Conversion & GT Rear Bumper

Some like to start with the exhaust, but it is proven to do little as far as performance. It is more about improved exterior looks and sound. I would save this for the end. You will need a GT or GT500 rear bumper or valance (for 2010 models) to get dual exhaust openings on the rear bumper.

Wheels | Drag Wheels Or Drifts

Wheels are completely up to you. If you are going all out for drag racing check out some of our SVE Drag wheels. If you are looking for something that is more for street/strip use I would look at a set of wheels that are wider and have a larger diameter such as our SVE Drift Wheels. This one is all about your personal taste.

In no way do you have to follow this step-by-step. If you would prefer to do these upgrades in a way that better fits your personal goals – go for it!

V6 Mustang Air/Fuel & Engine Upgrades

A proven way to get more horsepower and torque is to add a cold air intake kit to your Mustang. Intake kits remove the restrictive factory intake box, filter, and tube. It replaces them with high-flowing components that allow your engine to get more air which means more power! Companies such as BBK make performance cold air intake kits for the V6 Mustang. Check out our selection below. When doing any performance mods to a S197 Mustang a SCT Tuner is almost always a must. It allows for custom tunes, rear-end gear ratio changes, data logging, and MANY more features. If you want to maximize your intake system, don’t forget to add a performancethrottle body from BBK.

V6 Mustang Driveline Upgrades

Driveline mods for your V6 S197 Mustang can be some of the most “bang for the buck” performance modifications you can do!

V6 Mustang Dual Exhaust Conversion Parts

Nothing says muscle car like a dual exhaust system on your Pony car! Adding a true dual exhaust system to your 4.0L Mustang V6 requires a few parts. The outcome is a performance exhaust system that gives you more horsepower and a deeper more aggressive tone. The key components you need for a dual exhaust conversion are a mid-pipe (H or X Pipe), dual over axle tail pipes, 05-10 GT/GT500 axle back mufflers, and GT/GT500 rear bumper cover. Don’t forget to add a set of performance shorty or long-tube headers to maximize performance!
