Dear Sajeev,

I can remember many times where I’d hear, in passing, someone say that K&Ns and other performance air filters were actually bad for my car… daily or otherwise. Their argument was always that the performance filters allowed that 1 percent of dirt to get through. This argument came up again as Engineering Explained did an air filter comparison. His tests showed a small increase in power at a very minor risk of extra dirt (which seems to be less than 1 percent in many cases).

My question is: If an engine is an air pump and you’re filtering the majority of the dirty out, who cares about the 1 percent that gets through and enters the combustion chamber? When was the last time you heard of an engine dying due to dirty air? (Read More…)

I am currently at Bagram Airfield in Afghanistan where I will often find myself motoring around the Forward Operating Base (FOB) in one of the last generation Chevy Trailblazers. It is the straight six variety and it has undoubtedly led a difficult life. My requirements are few however…pretty much I need something that can do 25 miles an hour or so and not strand me on the other side of the airfield. As a bonus, the Trailblazer has a working AC and radio. What it doesn’t have is the ability to do 25 or so miles an hour regularly and get me back from the other side of the airfield. (Read More…)
