Cobra intake worth it?

pissedoff92 · Nov 19, 2011

Hey guys ive been looking into putting a Gt40 intake and head swap on my car for a while kinda waiting on the right deal to come up. I found a satin finish cobra intake with a 1" spacer and hes throwing in a set of factory 18# injectors. I dont need the injectors but he wants them to go with the intake. He wants 200 bucks for the combo. does this seem like a good deal and what can I expect performance wise?

If your stock, the Cobra intake is the best intake you can get. I personally love the Cobra intake. On a stock motor, you can expect 15-20 HP to the tires, every motor is a bit diff. 200 bucks is about right. Not a steal, but not to high.

how about that 1" intake spacer? is it a gimmick? I put a tb spacer in my f150 and all I noticed was an annoying sucking sound.

A spacer does two things, 1) it isolates heat from the engine getting to the upper intake manifold, which is a good thing, and 2) it lengthens the runner tract which tends to lower the power band (rpm wise), which on a near stock motor is okay, but not as desirable with say a big cam and head combo. I personally prefer a 3/8" spacer so I get the first benefit, without significantly affecting the runner tract length. The sucking sound you described may have been a vacuum leak from not sealing, you shouldn't hear the spacer. The Cobra intake is not the highest flowing intake around, but I agree with Kdubslugga, if you're running factory heads, it's an excellent choice. I ran one for years, including with Trick Flow Twisted Wedge heads, and it works very well.

thats a good deal, thats the same price i sold my cobra for with spacer......

GT40 Intake/Heads etc

Not too bad. Think I paid about $150 for heads and intake and TB at pick a part. That included my labor to remove. Should have gone on 1/2 off day in the fall/winter as it was Aug in Houston and a steam bath.

You may need to work on the heads too so keep that in mind.

Im gonna look into a pick a part around dallas area then maybe save myself some coinage

On my 90' I'm running GTP heads, Explorer intake and 70mm EGR spacer and throttle body with a cold air intake, a 73mm C&L Maf housing and 24# injectors. The bottom end is .030 over with a B303 cam. I couldn't be happier. I gasket matched the lower and head. Smoothed out the radiuses in the lower intake and blended the bowls in the heads just a little, you don't want to get carried away, and opened up the exhaust ports some. It pulls great from idle through about 3500 then it feels like it gets a 50 shot of nitrous and twists to 6000 before I grab the next gear. I drove a basically stock 93' GT the other day and the difference is like night and day. If I could have I would have run GT heads, but I got a smoking good deal on a complete 2000 Mountaineer engine. But then I had to find a 96' Explorer intake because anything newer doesn't have the internal EGR passage.

from what i hear im going to need different throttle body studs to mount it to the cobra intake

If you are running and EGR spacer with 190*-200* engine cooling water in it, the spacer does sqwat for cooling............

I ended up buying the intake today. got it for $200 bucks without the injectors but i didnt need them anyway. Turns out the spacer isnt one inch its about 3/8 i would say. luckily the guy was as bad at mechanics as he was at measuring because i had to pull the intake off the car. (i didnt know that yesterday) but the bolts were only in hand tight lol and he claims he ran it like that. either way I think I got a pretty good deal. Im happy. also got a set of stock valve covers for 25 bones from him. I got my car with autozone edelbrock specials that leak like a bastard and look like something from well autozone.

Sweet dude. Bolt that sum bit** up and make some more power!

pissedoff92 · Nov 22, 2011

Oh im looking forward to it! But before I do that I have a few other bigger issues, like my t-5 not going into second. And my pass rear axle tube is blown out of the center section. its gonna be a long winter

He was saying it would run cooler, he said the spacer would in a way act as an insulator to stop so much heat from soaking in the upper intake.

I understood what he said - did you understand what I said? A spacer does zero "cooling" good with a big chunk of EGR spacer aluminum bolted to the upper that has 190-200 degrees coolant and 1000 degree EGR gasses passing through it.

what about an egr delete?

tmoss · Nov 22, 2011

then you should turn off the EGR function in the EEC as it uses the EGR in fuel/spark calculations.

pissedoff92 · Nov 22, 2011

Now dont they make a plug that plugs into the egr plug that fools the computer?

On a related note, I currently have thumper E7 heads and stock intake with tmoss ported lower. Dyno'd at around 300fwhp.
Would a cobra intake likely show much improvement? Enough for the cost?

Yes they do, however the computer still thinks it will be getting EGR in the intake as it computes fuel and spark - but it won't be there will it? What could (not always) happen then?

Cobra intake worth it?
