Oh yeah, about the Downey intake... The Downey product is pretty simple and looks a lot like the K&N version. The mounting plate is a nice thick piece of aluminum. It comes with the holes pre-drilled for mounting it to the engine bay, but you need to drill your own holes to line up the air intake tube. The filter element seems well-constructed and I have just used the K&N Recharge kit to clean and lube it. With respect to performance gains, its hard to say. When I did this mod I also replaced the rusted out stock exhaust with a Magnaflow muffler and a hi-flow cat. Subjectively speaking, I do feel like the engine pulls a little stronger up Colorado mountain passes, but I try to stay below 4000 rpm and most of the "low hanging fruit" mods like this don't seem to do much unless you are really running the engine hard.

Hope that helps...
