Alrite im about to buy some intake and exhaust mods and i really like the dual inlet intake by slp but was wondering if it was really and better than the single or even other brands. Thanks for any help. Also only the camaro came with the dual stock on the tpi and i was wondering if i would have to do a lot of modification to the slp for a firebird with the dual setup. Thanks again.

 

I'm pretty sure that in order to install the SLP dual CAI on a 'bird, you have to relocate the battery. As far as possible gains over the single-inlet, I've no idea.

 

I think it'd have better throttle response than the single inlet, but overall either would be more than adequate.

 

If I were you... I'd just design my own. You'll save serious $$$

SLP wants something like $150 for their single setup and I don't even want to know about the dual.... if you really want to buy something from SLP... make it the runners they have for $250 and design your own dual CAI.

There are hundreds of designs you could spring board from on the internet to come up with your own. My only advice is to use good material when constructing it... don't just stick a dryer hose on there and call it a day... plan it out... this could be a really cool feature to your car that others will want to know how you did it. Have fun and keep us posted...

Word. Buying a new CAI unit often costs much more than simply making one. It's not hard at all. If you do a search on these boards alone you'll find tons of info too much to look through I imagine! The average cost of something like this is about 30-40 bucks and a couple hours of your time.

 

I personally don't think either of the SLP CAI kits are worth it, unless you find an awesome deal on them. From SLP's website, they want $190 for the single inlet and $300 for the dual inlet which you wouldn't be able to use easily anyway because of your MAF Sensor. These prices don't consider the time and money that would be spent relocating your battery and/or charcoal canister either. I feel like this is the same as the throttle body debate. The stock air intake up to the plenum and runners can flow well enough to support pretty big HP from what I understand. Take the $200-$300 you were going to spend on the SLP CAI, and spend it on something more useful like ignition and fuel delivery. Maybe some better runners or intake base, but those are just going to continue being suffocated by the cam and heads. Then maybe someday when you're making enough power that the stock setup is limiting you, or you're bored, have extra money, and need somthing that looks flashy, go with the CAI setup. Just my 2¢ though.

 

90-92 TPI don't have maf sensors.

The stock intake ducting does rob power it has been demonstrated on several occasions. I remember a dfi 7 discussion where they tested the effects with and without(just filter on TB) the ducting and there was a ~40hp difference. It was a long time ago so I may be off on the exact number but it was substantial.

 

regardless of test results and what SLP wants for their CAI systems... I think we all agree that for most people on a budget and well mostly stock cars.... making your own CAI setup is the way to go...

90FirebirdGTA... just make your own and buy something else for your ride. Assuming you have something like a few hundred your looking to spend... I'd say an adjustable fuel pressure regulator, 170 degree thermostat, BMR control arms, and a BMR panhard rod. And your home made CAI.

that way you get a lot for your money... a little horse power, a little cooling, and a little handling. All are easy to do if that is a concern.

I don't know the true gains of the dual inlet intake, but my idea has been to spend money on other things, and design an intake of your own. Its more hassle to relocate the battery and smog canister. I would think its cons are higher then its pros.

 

I definately agree with the diy cai just because of the simplicity of it and the fact that it is very hard to botch. I mean if you end up making a more restrictive intake while in the process of making a cai then you have no business modding your car.

As an Idea I'm having one custom bent for me out of exhaust tubing. Luckily my bro works in a exhaust shop and is hooking me up but it can't be that expensive to have one bent.
