I'm going to enter in 2 weeks a road rally. The last part I need to upgrade are the headers.

Before buying headers for my Z, I was just wondering if some of you got some over heating problem in the engine bay with any after market headers ?

Remember you have to remove the 2 stock heatshields when you install aftermarket headers. You have the fuel line very close and many other wires...

Also during long highway drive at over 80 mph (500 miles) did someone notice any overheating prb with aftermarket headers ?

Thanks,

Jerome

 

5,000 miles and no problems (knock on wood).

 

You can always get heat tape and wrap them when you install. people have c/o increased heat in the hood, and the problem would be worse if you are racing. heat tape or thermal coat will prevent most of the heat issues. also, remember to use new gaskets and get the headers retorqued a week down the road (as davidv will know)

 

I havn't had any problems

 

OK OK OK Rub it in. LOL.

headers - $450
installation - $200
second installation - $200

for 5 hp. WOW!

 

You think you got 5HP out of the Alphawerks headers?? All dynos show between 12-21RWHP gains.

Now im not so sure i wanna install them.
