I would think 06 would be the same as 05...
Depending on your engine size:

2006 Tacoma Aircharger Off Road kit 2.7 I4 63-9026

2006 Tacoma Aircharger 4.0 V6 63-9025

 

There's always ebay. That is where I got mine. Cheapest prices at that time. Probably still is. 63-9025.

 

i would go with the volant, i love mine and did a lot of reasearch before i bought one, none make a real big difference, from what i understand is afe is also prtty good.

 

I think I'm going with a Volant intake as well. The design looks to bring more cooler air in as the filter is completely sealed off from the engine bay. At least that's the way it look sin the pictures, where as the K&N definitely has some gaps that could let some warm engine compartment air in.

I figure they're all basically the same after that. I planned on installing an AEM filter regardless of which one I purchase anyways.

Oh yeah, here's a link to one on ebay:

I have the 63-9025 with the AEM air filter element. Don't recall the model number off the top of my head. If you want that info, PM me. I have the P/N at home.

 

aright thanx i think i could find out which one it is
