Best, I'd say Volant. Not cheap though.

Other end of the cost spectrum.

Shift kit, I'd start with the vette servo-VERY easy to install then if thats not enough go for a Transgo kit.

Edit: Sorry, missed the fact you were looking for a dry filter. AEM?

Sonnax makes probably the best "shift" kit out there for this transmission. This kit addresses pretty much all the major shift issues in the 4L60E making it shift real nice and make actually stand up to some decent power. This website calls it Sonnax Performance Pack and it is the second item down on the page.

Banks makes a pretty good cold air kit and it also looks ALOT better installed than most cold air kits.
