From your posts it seems like this is your first time under the hood. Air silencer is in your fender well. It is a plastic 'box' of sorts to keep the engine quiet. Under the front of the car in front of the passenger wheel and look up. That is the silencer (if it is there). It is bolted down by 2-4 bolts from the inside the engine compartment. So you need to remove the stock air box to get to the bolts.

 

Would a gt40 intake and plenum work good with gt40p heads.There is one on ebay and the guy said it is a gt40 intake off a explorer is that right?

 

ill check it for sure tomorrow but its the stock airbox with a k&n cone and im pretty sure it came stock with it. its a 94. ill check it out def. tomorrow.

 

yeah this is my first mustang. i already removed the air intake silencer . took me about 5 minutes haH.

 

No Mustang comes stock with a K&N filter and by silencer are you talking about the inlet tube in the fender.

 

yeah thats it

 

It is internally the same as the Cobra intake with larger runners than the stock intake. It works fine on the P heads and Non P heads.

Here is a comparison of the two intakes.



Here it is installed

 

I am getting this explorer intake and the guy is giving me 24ib injectors with it.
would i be able to use them with the stock motor or do i have to change?

 

You will need a MAF calibrated for 24lb injectors or it won't run right.

 

can you get factory 24lb injectors? the ones i got with the intake are factory ford ones.
and also I have the throttle body on the intake form the explorer can you use that one or can you use the one off your
stock intake? the one that came from the explorer is a little diffrent.
