Performance Parts / Replacement Parts

For the best performance and fuel economy, and long service life, an ample supply of only clean air should enter the combustion chambers of your engine. We make it easy to keep your engine breathing easily because we have everything you need to keep the clean air flowing, from the entrance to the air box right up to the cylinder head intake ports, including filters, mass air flow sensors, air intake hoses and intake manifolds.

Air mixes with fuel for combustion that drives the pistons and ultimately powers your vehicle. Most OE air filters are made of paper that’s formed into pleats. They work well for trapping dirt, but over time the dirt clogs the small passages in the filter, which restricts air flow and reduces power and fuel economy. Luckily, an air filter is easily replaced, and we offer all the top name brands, including the filter that’s right for your vehicle.

Just beyond the air filter box on most vehicles is the Mass Air Flow (MAF) sensor. This important component measures the volume and density of the air entering the engine and sends a voltage signal proportional to flow rate to the Engine Control Module (ECM). The ECM uses this information, along with input from other sensors, to calculate engine load. In response, the ECM controls fuel injector pulse width (injector on time), so the correct air/fuel mixture can be maintained for optimal combustion, the best power and fuel economy, and minimal emissions. Rough idle and stalling may indicate a bad MAF sensor.

Replacing your air filter is an easy do-it-yourself maintenance job. Another easy task is inspecting the air intake duct between the air filter box and the throttle body. All air entering your engine must be filtered by the air filter and accounted for by the MAF sensor. Any cracks, splits, or breaks in the ductwork can let additional air into the engine. Since this air has not been measured by the MAF, it can cause a lean condition with poor driveability, and the unfiltered air may carry dirt that could damage your engine. If you find any damage, we have the ducts and hoses you need to make your air intake system as good as new.

The intake manifold takes all the air from the throttle body and distributes it to the individual intake ports. Up until the 1990s, most intake manifolds were made of cast iron or aluminum, but then plastic began to supplant those materials because of its light weight, low production costs and superior heat dissipation. Unfortunately many plastic intakes proved to be not as durable as their predecessors, and developed cracks, warpage and internal damage. We carry replacement intakes that have been reengineered by the top aftermarket manufacturers to eliminate these defects.

    Auto Parts: Dealer vs. Aftermarket
    The question of whether to buy parts from an automotive dealer vs. ones from aftermarket manufacturers is as age-old as the automobile itself. Below, we'll take a look at things worth considering to help you make a better choice if you're facing that same question. Automobile manufacturers and dealerships always advertise the fact that their parts are "genuine" because they were made by the exact same production facility that made the parts installed on the assembly line.

    Why Does My Car Have a Plastic Intake Manifold?
    An intake manifold is an integrated assembly that sits atop the engine, consisting of a series of tubes which distribute fresh outside air to each and every cylinder. On V-shaped engine blocks, an intake manifold typically sits between the two cylinder banks while inline engines may feature a manifold to the side of the cylinder head. Intake manifolds serve as a mounting point for carburetors, throttle body assemblies, fuel injectors, thermostats, and more depending on vehicle manufacturer engineering preferences. Intake manifolds may also serve to route coolant through dedicated channels in order to remove heat from the engine. Because of their location and functionality, intake manifold assemblies are under constant stress from engine vacuum pressure as well as direct heat from coolant, cylinder combustion gasses, and the cylinder heads to which they are mounted.
