Hello, I've emailed you from 2 different addresses (one of them tends to be identified as spam I'm afraid) as I'd like to buy one of these. Please get back to me asap and we'll sort the rest out. I live in Nottingham. gimenofm@gmail.com

Installed my bracket today and very happy. Beautifully made and install on my 94 XJS was a snip. There was a palpable improvement in throttle response and acceleration. Fuel economy seems to have improved by a little over 1 MPG based on a 150 mile drive today that included lots of full throttle acceleration
A definite win-win scenario.
Thank you Andy!!
Cheers,
Allan

I installed it yesterday and it's as easy to install as everyone says, just depends on how rotten your bolts are.
I also have to join the club of the ones who say that the throttle response is significantly improved. About fuel economy I can't give any feedback just yet. Will try and go for a 100 mile ride next week.
I broke the old bracket so it's not like I'm going back to the original anyway haha.

Can I chip in?
Andy's bracket improves power and mid-range response. My car will happily run on 98 RON petrol with no 'pinking', using this bracket. My 0-100km/h times dropped 1 second (from 9.9 to 8.9 secs - a 3.2 X300).
Coupled with a K&N pod filter (remove airbox), top end is markedly better, and I would advocate bracket plus pod filter (no 0-100 km/h time yet).

The pod sits in the front left corner of the engine bay, gets a bit of cold air through from the lights - just like the standard filter box pipe does. It is on the inlet side of the engine, so the exhaust is on the other side, and has heat shields.
Having said all that, it is winter, and things might be different in a typical Hawkes Bay or Hamilton hot summer. But I don't spend much time in traffic, usually moving, and I doubt a 3.2 generates anywhere near the under-bonnet temps of an XJR or V12, so I am not too worried.
As far as I can tell, the X300 engine bay would be a difficult one to get good cold air in to, short of removing a headlight.

Well, the car definitely goes better. More surface area than a panel filter in a box, and less restrictive pipe length.

I might see if I can get my friendly local sheetmetal man to make me up a baffle to keep the hot air away and then I will get a pod filter for it...

the thin sheet cuts well with tin snips - have a go yourself!

Hi I recently just did a lot of work to my 96 XJR to get it back on the road. Performance intake from Mina Gallery New Coil Packs plugs valve cover and gaskets along with cleaning the intake from the supercharger... I'm 26 years old and I have been doing all the work on my car and I am finding that these cars are not easy to work on (octopus hose).
Anyway I'd like to see what the difference is when you apply this upgrade to a supercharged x300. I haven't read any posts from any owners I'm only seeing the naturally aspirated comments. But I'd really like to get a little more out of this sweet engine. The stock low end torque always roasts the tires and I love seeing the look on peoples faces when you make a big car like the xj move. I've beaten Sr20 powered 240sx's and mustangs and camaros. But if i could get this puppy to run with the bigger displacement american cars I'd love it.
Also I'm looking into upgrading the exhaust too. What diameter piping would be best to use for this engine?

Anyway, the bracket is great.
I would also recommend to cut off the snorkel and make a big hole on the side of the air filter box. Then you use a flexible, spiral reinforced hose (Diameter 140 mm if I remember right) from kitchen ventilation.
The hose fits perfectly in the precut hole in the left inner ving. You just have to remove the rubber thing that covers the hole.
Voila!

I was a bit worried that a lot of dust would enter via the intake but it have not yet on my car. I checked the filter after 1000 km driving and it looked completetly clean.

Hi James,
I have emailed you directly.
Dear All,
I took delivery of another batch of brackets last week. This takes the total production to over 260. If anyone wants one, then please get in touch at andystodart@metronet.co.uk
