Can I put a cobra upper and lower intake on my 91 LX 5.0 if so what will it give me and do I have to change the throttle body? What all do I need to do this if it is worth it before I purchase the parts.

It will fit your 5.0 engine. You may need a spacer depending on your valve covers. It would be recomended to get a throttle body & EGR spacer the same size as the throat opening to maximize the performance gains from the intake.

thank you How much difference should i see and is this a good thing to do

[FoxTrotPony]

Is it mainly a stock setup now?

[nden1423]

Yes it is all it has is underdrive pulleys and cold air

[FoxTrotPony]

You can expect at most 15-30hp gain if you use the throttle body & spacer with it. Then if you add heads/cam/1.7 roller rockers it will help gain even more. More air flow the better!

thanks for your help just tring to get some good advice on what the best way to mod my stang with out getting to out of hand any other ideas

GEARS!! rear end gears will give you the most "seat of your pants" feel for the $$ I put 3.73's in mine & kept the stock 26" tires, it woke up quite a bit & still had a good rpm @ highway speed.

[nden1423]

sounds good I think that I am going to put 3:73 in it and cobra intake, headers, what throttle body should I go with? Will that be a good thing to do and I should get some good power with that.
