Carbureted & EFI For Increasing Performance

High-Performance EFI Auto Repair in Lancaster

The expert mechanics at Royal Auto Repair 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, Royal Auto Repair 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 Royal Auto Repair and talk to us about increasing your car's performance. When you want performance you need the auto repair experts at Royal Auto Repair located at 60 Packard St.

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

Tuning Old School Carburetors For True Muscle

Your muscle car may be starving for air! Bring it to Royal Auto Repair 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. Royal Auto Repair 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 Royal Auto Repair at 60 Packard St to tune the perfect air to fuel mixture and correct ignition spark for maximum power.

John and staff are awesome. Had an exhaust problem that needed to be resolved and they jumped right on it. Could not be happier with the response and action taken to repair the problem and get me back on the road. Many Thanks!

My father took all our vehicles here since I was a kid and I?ve continued the tradition to this day. John, Larry and now Bjarne are and always have been those local trustworthy mechanics you want to do business with. They fix in a timely manner, have been honest when it?s not worth fixing, and are always sure to do the job right. From fixing my car to providing tips and advice when I wanted to do it myself, these guys are the best. Always bring you car here!

John just replaced the engine on our 2004 Camry. He has taken care of our car for the last seven years and we could not be happier. We look forward to another 250,000 miles on our car!

My family has been bringing their cars here for years. John is very honest and fair, and if something goes wrong, he'll do what he can to make it right. That is extremely rare as far as mechanics go. Those reasons are why I'll continue to bring my car here.
