You can gain access to the screws for the oil filler tube by removing the alternator. No engine R&R required. Thanks for your input...you have PM. Thanks.. Dave I've just been looking through the Porsche parts list with a Porsche 'independent' here in the UK. It looks possible that the larger X-51 throttle body may well fit to the standard intake manifold - the gasket part number is the same for both, so the bolt centres must be the same! We are looking at buying an X-51 airbox, hose, throttle body and oil filler tube to see if they can be fitted directly to the standard intake manifold. If they can, it will be the best 'true' cold air kit ever made for the standard car! We will also be doing before and after dyno runs to see if there are any gains. FWIW, cooler intake temps SHOULD equate to better power due to higher charge density. The X-51 airbox draws entirely cool air from outside the car where the standard airbox also draws hot air through the bottom of the box on the RH side. There's also the possibility of the engine breathing slightly better due to the design of the box and the bigger throttle body. Then again, the standard airbox / throttle body may not be the limiting factors so there may be no gains at all. Will report back in due course. We are also going to be trying the cams / exhaust / ECU upgrade from 9ff in Germany. This offers (claims?) 395BHP with no airbox mods. Again we'll be checking the validity of the claims. The independent I'm speaking to in the UK has just taken on the franchise for 9ff and will use my car as a test mule. Interesting times ahead!! Ian W Ian i was looking in to this as well, my carbon fiber box came in last week, mine is 3.6 engine. keep us posted on your progress. cheer Ronnie

we are not talking about the just replacing the euro springs, its the whole euro 20 mm sport suspension , which included, new sway bars, new spring , struts, bushings.

I am planning on doing the same thing. that is the only way to go. where did you get the part numbers from they are not available in the us ronnie

Hullo fm540i I have been thinking about this for a while to retrofit the x51 airbox , but I have a c2, I wonder if it will work on a c2. price sounds really fair. I see you are from chicago , so am I. what part of chicago are you from. Ronnie

I am planning do it the same thing. I have a base 997 (non s) with 18 inch wheels. is your car a base 997 non s, and does it have 18 inch wheels with the 20 mm suspension. I noticed on the porsche website in europe when you opt for 20 mm sport suspension it forces you opt out the 18 inch for 19 inches, so I am wondering if you did the same. thanks Ronnie
