Define best?
Each manufacture (and every customer) has an opinion on them, but it would help to narrow down what your looking for. K&N is the classic, but their QC has slipped over the past few years. Green filters has stepped up as the high end light oil cotton gauze filter with probably S&B and airaid for the heavier oils. Now truflow is probably the better filtering media with decent flow rates.
For the tubing, it's another hot discussion. Metal vs plastic, silver/white metals reflect light and possibly heat. The darker plastics better isolate the interior from exterior, but some think it absorbs heat more. For my money it will only be plastic, less heat saturation, easier to keep clean and looking nice. For design, the idea is velocity and you want the straightest shot for highest velocity. I think K&N's tubes are the best.
To those points, my dream system is a K&N FIPK with a Truflow replacement filter.

thanks for your opinion and thanks for the welcome! have got some great advice already!and your thoughts on the air induction is right on target with mine! of course everybody i talk to has a diffrent opinoin but alot of people have the same as we do. im figuring about $450-500 should do it! thanks again!

If you do an online search for “air filter test” there is a lot of very good information. IMHO, the CAI units are NOT WORTH THE $$! Unless you are talking about a system that was specifically designed for a specific application there are very little hp/tq gains actually achieved in a street use vehicle and there are very few docs that these mfg’s can produce that actually show an increase in hp/tq in the power-band range of a relatively stock street vehicle.
I would avoid oil impregnated filters. While they have their purpose in off-road applications, Ford/GM/Dodge all have “watch-out” bulletins where the oil has contaminated intake sensors. - they even have a training video for the tech's on this (flatratetech.com) .
If you look at the flow data, WIX HP filters flow 98+% of K&N and have a much smoother flow post filter plus excellent filtering, for a fraction of the price! The OE’s have an excellent air intake system the only issue that really exists is the plastic intake tube with it’s noise canceling design- that does reduce the intake efficiency a little but makes it very quiet!. You can use a WIX OEM HP replacement filter in the OEM plastic manifold box and either remove the plastic tube and replace it with a piece of pipe/hose, etc or remove the tube completely and replace the tube by building an air ram type intake into the air box manifold (where the pipe use to attach)- make sure ti terminates above the fan shroud to avoid water intake or fan induced pulsations.

They do have "universals" I had spec'd one out for my FIPK, but my dist never stocked them and I hated doing special orders. I can't seem to get into their catalog, but they had one that would work.
