[svtcobra03]

signs that my shits fucked?

[Your Name Here]

Doubt it. Use carb cleaner to find the air leak

[svtcobra03]

i got a coolant leak...that tends to leak like once every 3 weeks.

Time for a new intake

Does the 03 still have the plastic inlet on the manifold? That's where mine cracked. It was barly noticeable. The new ones are aluminum across the front.

There $199.99 New @ DALLAS MUSTANG

There was a huge recall on that plastic manifold for coolant leaks/cracks. Though if you didn't buy the car new, forget about it and call Jeremy at DMP, you can't beat $199.00. Pretty easy to install too or get you an aluminum badboy.

Anyone know if the recall is still valid? Looks like mine finally took a dump and is leaking into the engine valley.

03 had the aluminum coolant crossover in the front

[GrayStangGT]

Had my 01 crack on the backside, they aren't too bad to change out.

They stopped honoring that back around 2006.

I figured it was too old to honor. Thanks for the confirmation. At least I didn't have to drive into Ft Worth to find out.
Replacement suggestions? I'm seeing FRPP and Doorman. Thoughts?

[shumpertdavid]

The Dorman has smaller runners than the factory part. I believe it was CWO that cut one open to compare or he found some info online showing it. Anyhow there was a noticeable performance difference when installing a Dorman on a PI motor over the factory intake. Dormans was restrictive.

[CWO]

I didn't cut one myself, but I did some research and found a couple of people that did. You don't want the Dorman if you care anything about performance. Lots of information out there as to why, but basically the runners are non-pi with pi ports.

I have a used one I can sell you. I also have a bunch of performance parts for sale. LMK
