I need to replace mine and the STR one is $00 while the regular Stype 4.0 one is only like$150...

2003 Stype R

 

I have never tried to fit one but the STR item has a diferent part number to the non SC cars.
There is also a part number change at vin N13088.

See this page from the official on-line jaguar parts catalogue, to see if the cheaper one will fit with your vin number:

In theory you should be able to make it fit

 

Anyone have a picture?

 

I'll try and find it but if it helps I removed a belly pan from a 2005 XJ8 and it was a direct fit onto my 2004 XJR

 

Don't have a picture.. but my 2003 4.2L one looks different than the one posted in this thread (mine is more square) -> https://www.jaguarforums.com/forum/s...06-str-220754/

 

my car came without the front half . i checked and they are quite different to the regular s type .
way more venting on the str . some different access holes as well .
i bought mine new from jaguar for $700 nzd
