Cooling

Optimize cooling system performance and heater output with quality belts, hoses, parts, and approved fluids from ECS Tuning. Head off expensive repairs and untimely breakdowns with regularly scheduled cooling system inspection and maintenance.

Emissions

Repairing failed emission components doesn't just turn off the check engine light so you can pass you local emissions test, it also improves performance and fuel economy. ECS stocks all common emission controls, from oxygen sensors to PCV valves.

Intake

All engine performance begins with engine breathing. That's why we have a large inventory of stock and performance intake manifolds and related components, including MAF sensors, intake hoses, cold air systems, and filters for both normally aspirated and forced induction engines. To live long and perform well, your engine must breathe clean and breathe free.

Mount

Worn or torn engine mounts create noise, harshness, and vibration in the drivetrain that transfers annoyingly to the cabin. Broken motor mounts also pose a threat to safety. Regularly inspect and replace any engine mount that show signs of cracking, looseness, or other damage.

Timing

Prevent catastrophic engine damage: replace your timing belt and related components every six years, or at mileage intervals recommended in the your vehicle maintenance schedule, whichever comes first. Buy individual kits or purchase our famous timing belt service kits, complete with all the parts and fluid needed for a professional quality timing belt service.
