Abbas,

I'm not overly educated on K&N intakes, so my opinion is just a suggestion.
I went for the FIPK b/c it looked like the best bang for the buck (and it
was the only type offered on eBay.....that I could find anyway!). If K&N
offers a cold air induction (CAI) kit (i.e., the filter is placed outside of
the engine bay in the fenderwell to maximize cold air 'suction'), go with
that one as opposed to the single tube-based 'warm' air intake. Forced cold
air is slightly more effective and efficient than forced warm air.

As to the best of my knowledge, most of these K&N kits come equipped with a
heat shield to minimize the amount of engine-heated air that enters through
the filter. As for plugging the fenderwell hole, there's no need. Keeping
it open may provide a small source of cold air which is beneficial anyway.
The only potential problem is water that is splashed onto the filter from
the fenderwell which gets sucked into the engine....but depending on who you
talk to, moisture can actually help, not harm, your engine.....and your
fenderwell should be well-sealed anyway, so there's little to worry about
(after all, the stock air induction system received its air from here,
right?)

Anyway, the FIPK system works well for me, but if one of those other systems
on your list offers cold air induction, I'd go for that one (the cheapest
one of course....they're all essentially the same!).

BTW, gears and shift kits will give you that nice jolt off the line, so
that's definitely a good move as well.....just be cautious of both the
product price and potentially enormous installation costs if you're not a
do-it-yourself mechanic! But want to reinforce that inake?.......replace
those stock mufflers with a set of magnaflows. You'll get increased power
and a nice 'roar.' Or if you're looking for more moderately easy bolt-ons,
try an underdrive pulley replacement kit.

Anyway, good luck with it and have fun!

Just A Guy
