About us

At Road And Track Motorsport, we take pride in ensuring that you get the best service and satisfaction. We possess over decades of general maintenance and automobile restoration experience, and over 20 years of high performance upgrade and race car preparation experience. We specialize in European and Japanese vehicles. We drive the same cars we work on, in particular Audi's, BMW's, Mercedes, exotic and classic cars. Road and Track Motorsport is headed by Sunil Tennanrangam, who just like all enthusiasts, started his wrench turning helping his late father – who was a stellar and experienced mechanic. The family trade continued, and as Sunil grew of age he joined his father in maintaining the fleet of vehicles owned by the King of Bahrain at the time. After many years of working on a plethora of sports cars, exotics and luxury vehicles, they immigrated to the US. Soon after, they opened in 1997 R&T – specializing in the same kinds of cars they were used to working on overseas: Audi, BMW, Porsche, Volkswagen & Mercedes-Benz. Sunil is fully ASE certified and is a graduate from the London Chelsea School of Aeronautical and Automobile Engineering. With his father, he performed numerous restorations and does general maintenance work on a regular basis.

What is a tune up?

Gone are the days when TUNE-UP consisted of merely  key ignition system parts like spark plugs and ignition points, along with some basic adjustments to help "tune" the engine...With modern cars the following systems should be inspected:

  • Battery, charging and starting
  • Engine mechanical
  • Powertrain control (including onboard diagnostic checks)
  • Fuel
  • Ignition
  • Emissions

The following simple and inexpensive preventive checks will greatly extend the life of the vehicle, ensure safer operation and even benefit the environment.

Always consult your owner's manual for individual service schedules because maintenance requirements vary by manufacturer

Always consult your owner's manual, but a good rule of thumb is to have the oil filter changed regularly - every 3,000 to 4,000 miles.

Have all fluids checked, including brake, power steering, transmission/transaxle, windshield washer solvent and antifreeze. These fluids play a large role in the safety and performance of the vehicle.

Check tire inflation. Under-inflated tires can result in a loss of fuel efficiency. This is the least expensive form of preventive and safety maintenance. Tires should be checked once a month.

Keep your engine tuned. A fouled spark plug or plugged/restricted fuel injector can reduce fuel efficiency by as much as 30 percent.

Have the chassis lubricated frequently. This step extends the life of the moving components of the vehicle's suspension system.

Check battery cables and posts for corrosion and clean them as needed. The battery fluid also should be checked and filled if it is low, unless it is a maintenance-free battery.

Have the lighting system checked frequently, including headlights, turn signals, and brake and taillights.

Check windshield washer blades for cracks, tears and windshield contact. Replace them at least once a year, or sooner if streaking begins.

Inspect engine belts regularly. Worn belts will affect the engine performance. Look for cracks and missing sections or segments.

Have the air filtration system checked frequently. The air filter should be checked every other oil change for clogging or damage. This system ensures that the vehicle is performing at its peak condition.
