Hey Guys,

What are the differences between the 03 and 03.5 Coupe? I'm installing some headers for my 03 and they do not fit, wondering if this may be one of the reason. As of now it's hitting the steering rod. The header themselves bolton fine with the block and the Cats.

Thanks,
Gabe

 

uh, that's odd, as far as I can tell only real difference is that the 3.5 came with tire pressure sensors.

 

There was another member here yesterday with the same issue, headers not fitting as advertised. How far off are they from fitting, there's always the hammer option if were talking 1/6" any more and I'd forget the install. Headers are only worth 3 HP so HFC's are a better way to go....

that has nothing to do with your fitment problem.

03.5 has upgraded armrest console, sat radio prewire and improved 6 speed transmission, that's it.

 

You are right, I had one blk/blk 6mt waited 6 months for that but now I got 06 At . I miss my old 3.5 g35c 6mt it was a fun car. I'm happy to see some old member is still here.

 

also the 2003.5 uses electric radiator fans while the 2003 uses belt driven
