After installing a Flowmaster muffler on my 2009 Ford Ranger XLT, I have decided to add another mod. I am planning to install a cold air intake, I heard that it improves a vehicle's horse power and fuel consumption. What brand should I go for?

K&N as well as AirRaid I have used on my autos and been pleased with both. I like the quality of either of these products over other brands I have seen out there.

 

Some good options from both companies for your truck.

Just make sure you pick an intake where the cone is sufficiently isolated from any hot engine bay air. The term "cold air intake" is such an overused misnomer. My car had a cold air intake from factory, it was a sealed airbox with tubing leading away from the hot air under the hood. There are intakes that replace the box with a cone and claim to be a "cold air performance intake" that are the exact opposite of their advertised improvements.

 

All I'm saying is be mindful of the purpose: cooler air and higher volume of flow.

 

Try searching for the big name intakes on the Ford Ranger forums out there. Other people are sure to have installed and reviewed them with long term impressions.

How much gain can one reasonably expect from these? Any difference for turbo engines?
