Other future mods planned? If nothing major, any aftermarket (K&N, Vararam, Airaid...) will provide basically the same improvement (which is very minimal, maybe 5HP).
Other options; zip or flip tie mod, Z06 lid for your box, cut bigger holes in your lid.

If you are going to add any type of Air Intake change there are two basic types: Hot air and ambient air. Veraram, Calloway, etc draw outside ambient air into the engine, the others draw heated engine bay heat into the engine. Other than sound the heated intakes add little change to the engine performance. All the advertised gains in the ads is the result of a tune. IF you change to a smooth coupler to the engine from the accordion one, that will slow the velocity of air entering the engine and can result with less HP. Any change from the intake to the cats will change some of the engine dynamics. Rather than adding parts piece meal it is best to start with a complete plan (goal) and then make the changes.

There are TWO kinds of INTAKES that people commonly reference.:Intake Manifolds & Cold Air Intake
When you said INTAKE, I immediately thought of the intake manifold.
Any 2001-2004 intake manifold would improve air flow through the engine.
If you want a better flow of cool fresh air into the engine, you really need something that gets its fresh air from the front of the car vise inside the hood area.
If you don't want to spend a good bit of money for that type of cold air intake, you need to MODIFY the one that you have.
Investigate the FLIP TIE MOD or install a ZO6 type cover on your OEM filter housing.

If you are talking about a cold air intake----No matter what manufacturers claim most all CAI's can only produce about 10 RWHP on a stockish engine The rest is all BS---On a highly modded engine with heads and cam headers--Yes in order to get all the benefits of those mods a CAI is a must---but again there is no magic there---it simply allows you to get the most from all your mods--

a stock ls1 looses 3 kpa from ambient at max hp. measured by stock sensor. thats through filter, maf, tb, piping and intake manifold. so 10 hp for cai might be too optimistic.
besides, air speed under the hood may be higher than the speed your driving at. not much hot air there imho. cai=b.s.

With a stockish engine a CAI will LEAN down the stock WOT AFR from the stock pig rich settings --normally like 11.5-1 to the mid 12's-- So a CAI even without tuning ( after the fuel trims learn out and settle to "0") can easily add 10 RWHP
Once you add major mods your WOT fuel can become lean where tuning your fuel with a wideband at WOT can net you even more HP with a CAI
Even a stockish engine with a CAI will produce even MORE than 10 RWHP with a tune---Bogus claims to me are those of 20-25 RWHP however I have seen 15 RWHP with a CAI after being re-tuned

You might be overlooking the differences in the density of the incoming air. With a real cold air intake I can have 84F air running through the MAF while in a stock system I might be running at 145-165F. The cooler air is more dense and as a result has more oxygen content for each 43 cubic inch of air going in each cylinder.

When talking to EFILIVE about getting MAP KPA readings above 100 KPA they tell me that those are in fact simply " false readings" If you get readings above 100 KPA that means that you are somehow getting some BOOST in the air intake flow above atmospheric pressure----That is basically impossible to get boost without a SC or turbo--
A CAI can cool down the intake air temps and have less restriction than a stock airbox But it cannot "pack air" into your intake system to create pressure above atmospheric or 100 KPA My opinion

exactly, but replace 100kpa with "ambient". also, by what magic would you get colder air by 80°f? the original intake is an cai already and even if not, go and measure the speed of air under the hood when driving. you will be surprised. therefore you get nearly ambient temps. under the hood.
