Although all the 99's were suppose to have had the fix according to SVT, which I'm sure they did, but some Ford mechanics were lazy and claimed they performed all the changes but did not. Also below is a typical scenario anyone buying a 99 Cobra now should consider...
1. Joe buys a 99 Cobra brand new
2. Joe has the HP recall performed which includes increasing the intakes CFM using one of two methods. Replace intake or extrude hone.
3. Joe wants more HP and buys an intake off ebay to have hand ported and finds out it's a pre-fix intake and is near impossible to do anything with. So Joe throws it in the closet and buys another post fix intake, gets it ported and installs it and makes more power.
4. Joe decides to sell the Cobra but doesnt want to sell the newly modified intake with the car, so he removes and sells it seperately. Now Joe needs an intake to put back on the car to sell it....Guess what? Yep, he installs the pre-fix intake for someone else to worry about.
5. Some poor soul buys the Cobra and wonders if the "Fix" was ever done. Takes it to the dyno and makes low power, yet SVT swears it had the fix done.
6. Guess what......there is no doubt in my mind that that has happened before to someone.
Take the car and get it dyno'd and get piece of mind.
