I did a search on here for any info regarding this Intake Manifold, but it yeilded zero results. If anyone on here has any experience with this product, good, bad, indifferent to another product, this is the info I'm looking for. It has a lofty price tag, but I like the idea of adapting the newer tech to an older design. Not to mention you can interchange it between a single or dual plane in one unit if so desired. Any direction or help with this product would be greatly appreciated.

My 2 cents so take it for what it is worth. After working in a GM dealership and seeing all of the problems GM had and is still having with composite intakes I would probably pass. Seem like the only real advantage it would have is weight. Even if you could change from a dual to a single plane(didn't really specify), changing a regular intake on a chevy small block is pretty simple and if your engine is optimized and tuned for a certain intake then I don't really see how having interchangable tops would be an advantage anyways

There's no purpose on a strictly street car.

Y'know I looked at it, and passede, for all of the reasons stated above....

Well I understand that the plastic doesnt hold heat as much as aluminum allowing a cooler denser air intake charge. Your goign to trim about 5-10 lbs off of your engine with this setup. But I am not a fan of the plastic intakes at all. Especially when fuel and air is going through it. Most of the intakes that come from OEM manufacturers that are plastic only flow air. I dont know about thier long term testing on this piece and the affects gas will have on it. In the long term.

This is why I don't impulsively buy things I find to be cool lol. I never even put the pieces together that the fuel has to flow through it, nor did I think about the practical advantage of being able to switch the top to single or dual. There really is none unless you have two dedicated carburetors already dialed in for each piece. Thanks for the input guys.

I know I'm digging up an old thread, but I just got my Car Craft June '11 Magazine today and they have a write up on these. So I figured I would attach info for later people that search on these.

4804 is the dual plane (DPR)
4802 is the single plane (TXS)
4801 is the tall single plane (TXR)

They state the 4802 (TXS) is basically a Victor Jr in height. The 4801 (TXR) is 1"+ taller in height.
Victor Jr peaked 504 tq @5000 531 hp @6200.
TXS peaked 512 tq @5000 520 hp @6200.
TXR peaked 520 tq @5000 559 hp @6200.

It has some nice looking features: Threaded rear coolant ports in the baseplate. The intake bolt holes look like they all have metal fittings to prevent over torquing a gasket. They basically say you can remove the upper intake and leave the lower alone except for adding some RTV on the edge of the runners. That means upper intake swaps without pulling out some coolant, distributor, and using the timing light to make sure your marks didn't get off on the reinstall. 10 lbs lighter depending on your previous intake for the racers that are looking at any weight reduction they can do. Will that weight matter to someone on the street? Not really 10 lbs would be like not putting that last 1.3 gallons of fuel in or whatever. They also have cloverleaf style flange which is suppose to help the mixture according to the magazine. Supposely 30 degrees cooler than aluminum, which the magazine couldn't even back up in there testing.

Overall at close to $600 for the lower and upper set, then another $390+ for another upper (so you could tune with them on the dyno or swap out intakes depending on what you want to do).

I'll pass on them. They probably use specialized gaskets which means you'll probably have to get them mail order from a big catalog or directly from AFR. It's not like blowing an intake gasket and just walking down your parts store and telling them you want the Fel-Pro 1206. I'd also be worried of durability. I had the polymer type on my Bonneville it cracked the internal coolant passage around the front EGR, which apparently is very very common in the GM intakes. If/when they make them in aluminum I might think about it.

Yeah if they can make a plastic two piece they should be able to do an aluminum. I agree on teh dedicated racecar (drag car) it would be fine. But on a street car I would not run them.

gm is having problem with these? news to me! honestly the ls1 intake does just fine. the lq9 and lq4 do fine for the most part... seen a few with issues there but again look at production numbers vs problems and none had fuel issues. the metal intakes had far more problems. the 2.4 and ecotec use one with no issues.

only composite gm has with a known "problem" is the early 3.8 upper this early design did not offer enough room around the egr tube and would melt through over time. they corrected this by making the opening larger giving the tube room to dissipate heat with out melting the plastic.

I dont see a problem with this..

First off, AFR is not GM, how the two can be compared is beyond me.
Secondly the advantage is in large runners, weight savings, and a much cooler intake charge that does and will make more power. That being said, I agree w/ the tuning aspects of being setup for a single plane vs dual plane. That part of it doesn't make much sense to me.
CarCraft did a test on it makin big #'s w/ a383, but they also have the latest and greatest AFR heads and a rather large Comp Cam w/it. For now I'm gonna watch this piece and see how it does??? Maybe I'll get one, maybe not. I am sure someone on here will get one and let us know.....

I may do it in a year or two, when I switch to a holley efi system.

I saw this old thread and thought I would restart it once again. I am planning on buying this intake this winter and dropping it on my 406, I feel that a 30% reduction in heat transfer is huge given these cars have absolutely very little in the way of getting heat out of the engine compartment. My biggest issues have been the heat that heats up the carb via the intake and causing problems when the temps are hot. I don't have any cooling issues, car will stay at 185* all day long but the heat that under the hood is horrible. I am in the process of finishing up my hood project where I took the original glass hood and bonded an L-88 hood scoop to it and cut some heat extraction slots into it to help get the heat out but I really think this intake would be a good addition. The latest magazine intake comparison put this intake at the top of the chart albeit the priciest one. The intake on my car presently is an air gap design polished aluminum unit, car runs great until the heat builds under the hood so I am going to give it try. So has anybody put one of these on their since this thread was started back in 2011?

I wouldn't mind trying this intake if they came out with a single plane AND a dual plane top with injector bungs already in for an efi conversion. Plus, being a porter the ease of porting this would be awesome.

That's what's great about this manifold, it has cast in nitrous bosses and you interchange between the single plane and the dual plane without having to empty your coolant since you do not remove the head mounting plates and also, there are no gaskets to leak since they use O-rings just like the oem's, all you need to use is some silicone for china rails and you're done. My plan is do fuel injection and I will probably use the FAST II system that just came out down the road.

Anyone make this into efi yet?
