xk8 modding questions

Coming from a Lexus IS300, I was a bit disappointed to see the XK8 didnt have much aftermarket. After doing some research recently I saw some people have things like a K&N cold air intake and an ecu reflash. I was thinking "no f*cking way!" but I cannot seem to find a place that sells these things except Paramount Performance out of Britain (I believe). Now are there really modifications available to the U.S. like this? Also I cant seem to find any rims with out bolt pattern. Can anyone point me in the direction of a website that sells rims and modifications? I already know of Mina Gallery and i have purchased and installed an Arden bodykit and a Mina exhaust and I absolutely love it but I just want to know what else i could do to my jag

I know this isn't much help, but you're going to have trouble finding many mods for the car. They were produced in very low numbers, therefore there's not much of a market for mods. But that's one of the things that makes the car so cool. I can drive across town and see a half dozen IS300's, but last summer I drove clear across the country and back and only saw two other XK8's.
By the way, I looked for a cold air intake a few months ago and learned 1) K&N doesn't make one for the XK8. and 2) most "cold air intakes" end up decreasing the vehicle's HP. In the case of the XK8 it gets its air from up under the fender. Many aftermarket intakes just take air straight from the engine bay, and that's going to be hotter than the air from up under the fender.

sorry to disappoint, but you are correct. There isn't much you can do to this model.
coventry west I think is the only 'big' jag bolt-on spec'd wheels. But with the right adapater (custom machined if you must) you can put anything on you want, with the right offset of course.
you can do HIDs if you don't have them...no idea what MY yours is, may want to put that in your sig. Tail lights have been swapped before, exhaust of course, poly-eurathane suspension bushings, lowering springs, grilles...that's all I can think of off the top of the 'ol head.
...not that I am recommending these personally, as it could affect performance and ride quality

As far as air intake is concerned the best you can do is one of these http://www.cbsonline.co.uk/remote-ca...bfil-861-p.asp
(I really need to discover how to do URL links
) You will need to run the pipe to somewhere near the front of the car....Colder the air the more oxygen the more power and besides that they are cheaper than a panel filter.
The best place IMO is www.paragondesignuk.com but I would say that
, you are right in saying there is not alot you can do to an XK8 unless you go mental
like me and I dont wish to keep repeating myself but this is just automotive ****

If those are the mods im limited to then I might as well do what I planned on doing and keeping the jag as my daily driver and build a 240sx for drifting

I like what you've done. That is the Arden Kit, correct? In time I would like to add them. Why not go with a Jaguar factory wheel from a latter model? I think there are some pretty nice designs, and it would retain a unique yet OEM look...versus Big Chrome Wheels that you can tell right off are aftermarket on everything from trucks to all your 4 door sedans. Aftermarket wheels are "fadish" that become dated looking; whereas Factory Wheels will always look right. Just my opinion.

I am afraid it jumps a lot when you get to XKR the only option is the BMC CDA air box which is the same but larger and can take greater demands, the smaller one for the XK8 is rated up to 350BHP the BMC item is good for 500+ but alas the price goes up to a couple hundred bux.
In my experience it is the only one that actually has some benefit, exposed cone filters sound good and you do get nice induction noise but it has been prooven you actually loose power because of sucking in the hot air from engine bay, and all because you have a heat shield dont go thinking that is your saving grace, because it isn't....
For a cheap trick if you are after induction noise get an early XK8 induction pipe as these dont have all the baffles in place to kill the sound like the XKRs, it's not perfect but it really depends what you are after.

i know about hot air in the engine bay and why exposed filters in the engine bay (such as short ram intakes) do not work. they didnt make a cold air intake for the is300 (well they did but it was discontinued) and i wasnt going to go with an injen intake when the factory air box worked better cause it had a ram air type thing that sucked cold air right from the front of the car so instead i went with a joe z intake which replaced the factory intake tube with a direct flow tube and used a k&n drop in. i figured maybe there was an intake for out cars that went into the front bumper or the fender.
