You've probably felt the drain on your engine when your air conditioning compressor kicks in. But did you know that your other accessories are taking a similar toll on your power all the time? It's because of the way your Acura pulleys were designed. Acura engineers designed the stock Acura pulleys to provide more than enough alternator output, power steering boost, and A/C output. By changing your Acura pulleys to provide "just enough" power to those accessories, you can free up horsepower to be used at the wheels. And all you need is a set of Acura performance pulleys. Our Acura underdrive pulleys reduce the amount of engine power needed to drive your accessory systems. You still get good alternator output, A/C cooling, and power steering with an Acura pulley set. You just don't get the extra capacity of a stock Acura pulley set. But if you're the kind of driver who wants his extra power to shave tenths off at the dragstrip, not to run a power steering pump, then our Acura pulleys are an easy modification with great results. We have Acura pulleys available for a wide variety of Acura vehicles. Each Acura pulley set is designed to work with a particular engine/vehicle, so you'll get great results every time. And when you order your Acura pulleys from us, you know you've paid less for your Acura pulleys than your competition has.
