Performance Parts / Replacement Parts

One of the easiest ways to get more power from your engine is to dump the OE air filter and air intake system and replace them with high-flow aftermarket parts. Factory systems are designed with priorities other than performance, like low intake noise and cost. As a result, most vehicles come from the factory with restrictive air boxes and intake tubes, and cheap paper air filters. Choose a system from our vast selection and make your engine come alive.

An inexpensive way to start is just by replacing that paper air filter. It filters the air OK, but the small passages are very restrictive, and as dirt builds up, flow gets even worse. A typical aftermarket performance air filter has several layers of filtration material like cotton gauze, which traps dirt without restricting airflow. What’s more, aftermarket filters can be cleaned and reused, so you get increased engine power and save money to boot.

But to really get an increase in airflow, you need to increase the size of the air filter. The typical conical air filter that is included with an aftermarket performance air intake is not only made of better material, it is larger and has much greater surface area than the OE filter, for much greater airflow. An economical way to get the benefits of a larger filter is with one our kits that attaches the filter to a flexible, universal intake tube, or attaches it to the factory air intake tube. The next step up to greater airflow is to replace that restrictive OE air intake tube.

Most factory air intake tubes are constructed with the goal of keeping air intake roar to a minimum. They usually have awkward bends and have sound baffles, which may reduce noise but can also restrict airflow. Aftermarket intake tubes are constructed from mandrel-bent aluminum or molded polyethylene, with larger diameters and smoother bends, for better airflow to the throttle body. And if you’re a hot rodder, you’ll consider the increased intake noise music to your ears when you stomp on the gas. A basic performance air intake will replace the factory air box and air intake tube, and install in approximately the same location.

The next step to more power is to feed the engine cooler air, which is denser and contains more oxygen, for better combustion. We offer systems that employ varying methods to shield the filter from engine heat so it can take in cooler air. Some systems have barriers that seal against the hood, to separate the filter from engine heat. We also have systems with an air box, which not only shields the filter from heat, but is much larger than the OE unit so it can hold a much larger filter. For exposure to the coldest air, some systems locate the air filter outside the engine bay, or use a scoop to funnel air to the filter.

To get the most horsepower, airflow should be increased all the way to the cylinder head intake ports, and we have the performance MAF (Mass Air Flow) sensors and throttle bodies, and high performance intake manifolds to make it happen. Our MAF sensors are not only larger in diameter to pass more air, but they’re also calibrated to ensure the PCM (Powertrain Control Module) gets an accurate signal so it can properly control the air/fuel ratio. And whatever your engine’s state of tune, from mildly hopped-up street machine to an all-out track beast, we have the right size throttle bodies to increase airflow and horsepower, and provide crisp throttle response.

The intake manifold is the last leg, and in some cases the most important part, of the airflow journey, where air or the air/fuel mixture from the throttle body or carburetor is distributed to the individual cylinder head intake ports. Like the OE air intake tube, factory intake manifolds can have runners that are too small in diameter, with bends and contours that are not conducive to maximum airflow. We offer manifolds developed by the top brands in the industry to have the right amount of flow and velocity to suit every type of use and horsepower level. And finally, you can reduce crankcase pressure, improve ring seal, and make more horsepower with one of our external crankcase vacuum pumps.

    Can an Air Intake System also Increase My Fuel Economy?
    We all know that achieving better fuel economy while driving puts money back in your pocket and does the environment a favor. But for those who are actively interested in squeezing the most out of every drop of gas, getting more miles per gallon can actually become a sport - especially if a vehicle has a manual transmission that can be upshifted earlier and put into neutral during downhill grades or when coasting to a stop sign.

    The Real Cost of Your Car’s Cheap Factory Air Filter
    In today's world, saving money wherever possible has become essential. But it's important not to lose sight of the fact that, sometimes, a product that costs more up front will save you more money over time. In our business, we've seen far too many consumers judge products solely on the basis of their initial cost, completely neglecting any long-term economy and benefits. When it comes to automobiles, "performance" air filters are a perfect example of this.

    My Car is Brand New | Why Should I Change My Air Intake System?
    Aftermarket air intake systems have become one of the most popular engine modifications available for late model cars and trucks. An easy question to ask is why are these so popular? After all, didn't engineers who work for your vehicle manufacturer spend years developing the best engine components available? Since power and fuel economy are major selling points these days, it's hard to imagine car companies not doing everything they can to maximize horsepower, miles per gallon, or both.

    What are the Different Types of Air Intake Systems?
    There are many types of aftermarket air intake systems that range from simple and inexpensive to elaborate. In the scope of this article, we'll examine the different types of air intakes, what they do, and look at a few specific product examples of each. But in short, performance air intake setups increase airflow into your engine - boosting combustion and creating more horsepower and torque that you can actually feel. Their relatively low cost and easy installation (bolt-on in most cases) keeps them in popular demand by car enthusiasts that own everything from 1.5-liter turbo motors to big block V8 engines.

    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.
