Difference between 1998 and 1999 Cobra?

The things that I know are different between 1998 and 1999 Cobra's:

- IRS
- 15 more HP (returnless fuel? coil-on-plug?)
- Body style, obviously
- Traction control

What are the other significant technical differences? Assuming the HP fix has been performed on the '99, is there any good reason to avoid it (body style doesn't count :-)).

TIA.

The heads have a different design. The Intake is also different and If I remember correctly it did not use IMRC plates.

I do know when you port the 99 Heads they are tumble ported and the 98 heads have to be Bowl ported. Correct me if I'm wrong.

the heads on the 98 are swirl port type, and the 99 are tumble port... this is why the 99 was able to do away with the IMRC's.. it produced enough torque down low that they were un-necessary..

I think the interior was slightly different.. (not sure on this though) and the gauges no longer have the writing on them such as NORMAL for the water temp..

have 2003 Sonic Blue Coupe, parchment seats on order.. I have the VIN # 1FAFP48Y23F302629 WHOOOO.. born on 23 July, shipped by convoy carrier 28 July, scheduled delivery 5 Aug..

98 still had the "6" cats I believe where as the 99 went down to "4". I have a friend who has a 98 I will ask him.

A minor change noted was in '99, Ford started using Brembo rotors up front.

Well, I think my decision has been made for me.

Here were my choices:

1999 Cobra Vert, Rio Red, 12.8k miles. Driven by a grandma who is getting rid of it because her arthritis prevents her from driving a stick. Downside: car has had a lot of idle time, and has not been driven since September (except when I drove it today). Price, $23k.

1998 Cobra Vert, Chrome Yellow, 7.7k miles. Never met the owner, someone else was handling the sale for him, and he wanted 26.5k for the car. I told him it would need to be far closer to $20k, and he declined.

So you can guess what my plans are. Tomorrow I expect to end the day owning another Cobra. This time a '99 :-). I know that the HP fix has been performed.

So when were these cars produced -- it looks like this one was sold in early August of 1999. Does that make it an early model or a later one? I'll have to call SVT once I get it and find out the build number, I suppose. Come to think of it, I'll just ask grandma for the certificate. She's keeping the SVT jacket, 'cause it's waaaay to small to fit me :-).

The only two problems with the 1999 that I can see are that it has been sitting for 6 months -- translation: it will be getting an oil change within the next couple of days, and won't see anything more than 3500 rpm until then. And it's got a ding from something falling off the wall of their garage. Not a bad ding (about the diameter of a quarter, and very shallow), I'm going to find out whether it can be fixed with "paintless" dent removal. Unfortunately it's at the top of the quarter panel, which is about the last place I'd like to see any dings.

Ok, sorry about all the chatter. I'm quite pleased, if you can't tell... spring is a comin, and I plan to be in a drop-top for it! :-) Yes, even in Oregon there is sunny weather occasionally. hehehe

Yum yum, got the 99 today. It really has been taken care of. The woman that owned it couldn't drive it, but it turns out that even so, it managed to make it in for regular 3 month oil changes. Nice. I'm quite happy. I was a little surprised at first how loose the body feels, but I guess that's the payback for having a ragtop.

Now I own *two* Cobra's :-). Anyone want to buy a chrome yellow 98 coupe?
