No matter what cab configuration it comes in, the 2005 - 2006 Toyota Tundra is a very sturdy mid-size truck and has become a fast-selling model in the United States and other markets. While some performance is sacrificed to keep the weight down, there's plenty to spare for all but the largest haul. However, engine efficiency can be increased by a significant amount just by adding a Toyota Tacoma cold air intake to the mix. You'll have a guaranteed increase in not only engine efficiency but also, improved gas mileage, cooler engine operation, more complete combustion and increased horsepower. Forcing a greater volume of air through the intake is like fanning the flame in each cylinder. If all the performance benefits weren't enough, the K&N Tacoma cold air intake kit installs in less than 90 minutes. It is designed and built specifically for your truck of the highest-grade materials. It isn't often such a significant increase in the performance of your truck can be achieved with such a reasonably priced, passive modification. If you enjoy saving money on gas and increased responsiveness from your car, the Toyota K&N cold air intake filter could be the best investment you've ever made.
