Stock replaceable filter in a K&N is part# E-0890 ('90 5.7 Firebird).

You can also get an open element cone style which is about 10" long and route it down and into the front corner of the fender / front fascia.

You can walk right in to any Advance Auto or Auto Zone and buy them off the shelf. At least where I am from you can.

The one that fits right over the throttle body is RC-5000. Just bought one i know it works and i know it fits. Oh yeah thats the K&N part # but im sure any autopoarts store can reference off that.

You can get the ones that fit onto the throttle body from jegs.

why would you want one? The loss of power of breathing the radiator heat has been discussed/proven many times.

FireBirdKnight · 09-11-2007, 03:38 PM

even with both cooling fans on?

it might be breathing in hot air but it breathing nun the less the stock system is so restrictive. i felt an increac in power swiching to the tb mount style so ill stay with it just my opinion

go cruise around town for a while, then pull off and throw the hood up - tell me you want to be kept breathing in that air. - The fans will help to feed it the rad air.

Anyone with some real data rather than theory?

I don't have the numbers for this specific application, but I picked up 7rwhp enclosing my 14" round carb filter and running 2 3" ducts to it back when I had the stock hood. - The differences of it being on top the motor vs at the front would have to be minimal.

I'm going to have to locate my timeslips and see what they actually say, I found conflicting posts... both my own

Anyway, I did a back to back at the track, with ducting to the stock TA airbox location, and with the MAF sucking air right off the radiator on a very hot day. I dont remember any real difference either way.
