      ok with the power package combo a computer tune is recommend how about bigger injectors? Im going to run a 2.8 upper pulley stock lower would larger 30#or 42#injectors with a tune give me more power or just stay with the 24# stock ones alter the pulse width timing? ? ?

      • It's certainly possible, however once a tune is involved the answer is entirely dependent on the tunes being written for your application. Because of this, the tuner themselves should be making the decision on any and all fuel components relative to your application.

      I installed the Accufab oval throttle body power inlet plenum in my 03 SVT Cobra , I turn my car on and I’m having a problem with high Idle at 1600 rpm I drove it coupe blocks to see if that would help it, goes down, but once I’m in neutral it goes back up? Any idea on what can be causing this high idle? Thanks for your help

      • You may need to adjust the idle speed which you will need to adjust the throttle position sensor (TPS) to adjust the idle.

          Little sticky, nice product!!

          Like others have mentioned, it's a little sticky, we'll see if it goes away. Too soon to tell performance gains, but will be tuned once the weather improves. Paired with JLT CAI. Easy, quick install and looks great under the hood!!

          Absolutely love it

          The item came quickly, was a lot nicer than I expected. Pictures don’t give this any justice. I installed the piece and it only took me an hour if that. As soon as I started the car up, I could instantly hear the difference, almost as if the car was breathing better, it was like a big gulp of air.Throttle response was way better and could feel the power instantly when I left the yard. Great product.

          Instant gratification

          I added a ported Eaton to my 03 cobra with little gains with a stock TB. After adding this Accufab setup, I felt and saw gains on the dyno. Added 30 more horsepower. Plug and play.

          Very pleased with this product. A huge upgrade compare to the factory one. You will instantly fell the difference. It is pricey but in my opinion worth it. I’m no mechanic but with a few tools it took me over an hour.

          5 2004 Cobra - mayosvt Installation Time: Less than 1 Hour

          Huge upgrade over stock ported tb and inlet

          Instant change in idle. Much smoother and throttle response was instant. No issues installing as it fit just like the stick piece. At start up, the filter was pulling in so much air it sounded like a vac leak. Ported eaton is much louder at idle and sounds like a vacuum at wot. Great piece but it is a little on the expensive side.

          03 Cobra Accufab TB Power Inlet Plenum

          I have bought various things from American Muscle. Excellent service and fast shipping every time. I have a 03 Cobra with a BBK throttle body that was sticking open. I bought the Accufab to try. Install took less than a hour and definitely has a lot better throttle response over the BBK. It does stick a bit when you first press on the pedal, but I'm guessing it's because it's brand new. Definitely better then my BBK. Pricing is higher, but well worth it for the Terminators.

          The product does everything it promises from initial start up u can hear the throttle body sucking air.. it sounds awesome and u can feel the instant power over the stock throttle body plus no sticking issues..it really compiliments the smaller pulley and intake I have well worth the money spent if u done basic bolts and havent added this throttle body and plenum this is next best thing I added over 27whp over previous dyno since adding this throttle body and plenum

          5 2004 Cobra - Cameron Installation Time: Less than 1 Hour

          Wild Child

          My Cobra was already highly modified and custom tuned. That having been said, after installing the throttle body/plenum the increase in throttle response and power was breath taking. I can't wait to get my car back on the dyno. It took me overnight to install the throttle body because the lower right nut on the plenum requires a stubby wrench and I started the installation late in the evening without one. The next morning I got the required tool at the parts store and I'd say my total install time was less than an hour. The Accufab Throttle Body/Power Inlet Plenum makes my Cobra much more of a wild child than she already was.

          I have JLT RAI pulley tune exhaust and this throttle body helped allot easy to install took 10 minutes felt the difference right away but it was sticky at first I had to clean the inside with carb cleaner now works fine. For low end mod it's the best thing to have. Didn't feel much of top end tho

          This replaced my already ported stock twin bore throttle body and plenum that was not allowing enough air in to fully realize my Cobra potential. The difference was instant even before tuning. I gained 53 rwhp after a tweak in tuning. I highly recommend the oval design over the twin port. The polished finish was very nice and added a great look to my 4.6.
