SLP Cold Air Induction
I am considering the SLP cold air induction from SLP for a 93 LT1 Corvette with MT and a Borla Cat-back. It is currently on special for $214.95.
Has anyone used this and saw some performance gains? Is it worth the money? Is there a better set-up out there? What other set=ups are there anyway? I really benefited from everyones recommendations on a previous posting. Thank you all in advance.

It's on special! Cool, now I don't have to wait till October. I have an October coupon for 10% off.
Plus I get to save on shipping, my coworker delivers there everyday.

Re: SLP Cold Air Induction (gabmando)
Oh, I forgot to answer, you won't see any gains, but you will get a WOW factor from gawkers.
A few guys at the track have tested them with no difference in performance.
I want it because it looks cool.

Re: SLP Cold Air Induction (gabmando)
is it worth the money, maybe.
will you get a real performance gain, prolly not but you could get slightly better in the 1/4mi from it
there really isnt a much better setup, none of them give a real increase over a open lid and K&N filter
but i'm buying the SLP part anyway, cuz i need a new airbox

Re: SLP Cold Air Induction (Mr Mojo)
I saw no gain with the open lid.
Like you needed to show any gains, Mojo! :jester But seriously, I think it is an awesome looking induction system and doesn't require you to cut your radiator shroud. I really didn't want to go with any of the airboxes that required cutting the shroud because my vette is daily driven and I didn't want to risk rainwater getting in. My revs may be a little smoother at higher RPM's, but overall I saw no big change from a cut-lid airbox and K&N. Plus it sounds pretty cool when you cut the car off....has a great "Whoooosh"!

Re: SLP Cold Air Induction (Dave95C4)
does anyone know if i could use this intake on my L98.....what modifications would have to be done? I know there slp makes one for the l98 but i think the claw looks cooler, and if its not gonna make a perf. difference, i might as well get the one that looks cool, right?

Re: SLP Cold Air Induction (C4Fetish)
I have had one on my vette for about 2 years now.. I like it.. Very nice design no mods to your vette, and can return to stock anytime.
I do not know about low-end gains, but I can attest to it helping me at high highway speeds.. When I did the mod (before and after) I ran the car from 100-140 and there was a noticeable difference after the SLP was installed..
I should mention also, that I enlarged the air intape port on it to double the size. It is made of a durable hard plastic, so it can take the air pressure well too.. The ONLY issue I have with it is the fact that it restricts the air movement to the radiator. The car runs a bit hotter now. With the hot temps in CT over the past 3 days (80+ and humid) even while driving on the highway at 60-70 the temps were around 215OIL and 200coolant.
I am going toremove the unit today actually to see hwo much my temps get affected by it. And I'll do a few runs to see how my ET is affected too..
I've been thinking of routing my fog-light ports to a ram-air setup for a while. Maybe ill do that to keep temps down..

Re: SLP Cold Air Induction (gabmando)
Gabmando, I would get a ram-air setup; check out offerings for your year in MAD. They require cutting an opening in the surface of the radiator shroud to pull air from the hi-pressure area in front of the radiator.
There is one ram-air that replaces the license plate and pulls air in directly.
C4Fetish, I have the SLP ram-air that scoops cold air from in front of the radiator. It requires cutting about a 3"*18" slot across the front bottom of the radiator shroud. This a great mod for those not yet running a K&N as it costs about $160 and comes with a (stock size) K&N. I saw about 5hp gain over the open lid which was about 5hp over stock setup. I think this on is definitely worth the $$.

Re: SLP Cold Air Induction (vader86)
Ok back with results..
I removed my SLP ram air system (same one you are talkign about, the one in front of the radiator scooping up air from under the front).
My temperatures were about 10-15 F LOWER on my oil AND coolant...
Of the line the car ran pretty much the same in the 1/4, but it is pretty humid and hot out so I couldnt do an EXACT comparison. The 13.39 I ran in a cool and dry night 2 months ago. (with a prefect launch ;-) ).
I did notice though when I did a high-speed run over 100 it did feel to pull a little bit less than usuall..I'm not sure..
I think I am going to leave the SLP ram air off though during the summer. Reduces my temps quite a bit to not run it.
About water getting in, I dont drive the car in rain a lot, but have not had any issues in the past 3 years.

Re: SLP Cold Air Induction (95Purple)
Open air lid, K&N, and an airfoil gave me 2 tenths in the quarter. I understand from more than 1 source the SLP doesn't give you anything over an open airlid. Unless you cut the shroud below the K&N so it can draw air off the top of the radiator.

Whoa...yeah this definitely sets a record. I read my post and was like "I don't remember posting that...haven't talked to Mojo in ages..." then I looked at the date!
Just so I'm not totally derailing the thread into off topic territory, I've still got the SLP claw installed 10yrs later and still haven't seen any gains. However, it looks great with an occasional coat of Zaino, the original K&N filters have held up, and it continues to make the same awesome whooshing sound when the car is turned off!

I heard the airfoil doesnt do really anything. I had an open air lid + the K&N and I went to the SLP with a new K&N. My 85 Z51 pulls slightly harder despite the temp increase. Im probably going to go to a big mouth air dam to counteract the ram air while actually increasing its output.

FYI, IBTL.
I actually went slower with a Open Air Lid w/K&N on a lower DA day, than I did with the stock setup on a higher DA day. Proved this on back to back weekends.
For stock and close to stock applications these Open Air Lids, SLP stuff is just bling. No gains what so ever. On more modified applications there maybe some gain. The stock LT1 induction/exhuast systems are so well matched to the engine itself it is just great engineering. The cam really is what limits you, then the heads, then......
