Carbureted & EFI For Increasing Performance in Essex Junction, VT

Carbureted & EFI For Increasing Performance

If you're ready to take your car or truck's fuel injection to the next level, Cousino Performance is ready with injectors, manifolds, fuel rails, sensors, and complete performance EFI conversion kits. From BMW to Audi to Corvette, Cousino Performance has you covered.

High-Performance EFI Auto Repair in Essex Junction
The expert mechanics at Cousino Performance know switching to fuel injection often improves the fuel efficiency and performance of older carbureted engines. In newer cars, replacing a single fuel injector with a multi-port fuel injector creates an intense, even flow of fuel on each cylinder when your engine needs it most. Feed your engine the fuel it needs with fuel pumps, fuel filters, superchargers, and turbochargers. Break out of gasoline only feed engines by adding a nitrous kit or cooling methanol injection kit.

To ensure the correct air to fuel ratio, Cousino Performance can add a new stock-height replacement intake manifold, cold air intake, and fuel rails. Never run rich or lean with a hood scoop, high-performance air filter, and new O2 sensor. Call Cousino Performance and talk to us about increasing your car's performance. When you want performance you need the auto repair experts at Cousino Performance located at 8 Saxon Hill Rd.

Tuning Old School Carburetors For True Muscle
Your muscle car may be starving for air! Bring it to Cousino Performance and find out. Because of operating losses in the intake runner and cylinder with newer unleaded fuels that do not fully vaporize in the combustion chamber, cars tuned to the manufacturer's specifications can run lean. Cousino Performance can diagnose if you are actually running leaner than the manufacturer suggested ratio of 14.7:1 air to fuel mixture. Bring your classic car to Cousino Performance at 8 Saxon Hill Rd to tune the perfect air to fuel mixture and correct ignition spark for maximum power.

Need to replace your old four-barrel carburetors or hack your hood with tunnel rams? Cousino Performance will help you choose the Holley, Edelbrock, Barry Grant, or Quick Fuel carburetor and air intake system that is right for your car. Call us today at 802-881-7559!

I had heard other’s testimonies about their experience here and decided to try it for myself. I had an inspection due and needed my summer tires put. Dan was attentive and efficient, he didn’t pull the wool over my eyes when it came to the bill (very much appreciated that)! I’m happy to have taken the advice of others and can fully agree - I will be returning for any service my car may need next!
