No. But your mind is made up so use the cobra if you feel its better. I feel its money pissed away in trying to fix a problem that won't be fixed with an intake. I went high 12's @ 109 untuned with this intake on motor. If you used the gt40 intake instead, nothing would change besides the even more emptiness in your wallet and the price tag of that gt40 intake is a JOKE. You want my honest opinion on what you NEED to do? Dyno/track race the car. Is the clutch slipping? Are you getting valve float? Are your old valve springs up to par with the camshaft? Is the camshaft right for the combo? Is the tune off? Ask yourself these questions.
