Cold Air intake
#21
Cei
After many years of owning cars and trying various CEI, even the Dinan set up for a BMW I had, which along with required downloads, larger TB and CEI and muffler cost over $2K. Also, putting a CEI on a Porsche and Audi A6. I found that there marginally effective at best. I never got a great gain in HP or Fuel mileage. The HP came from dyno testing before and after. I use K&N replacement filters in my cars and they work just as well as the CEI I've had in the past. If you want more HP a CEI is not going to give you what you think your going to get. This is just my experience, perhaps yours will work well, but none that I had did much if anything at all for performance. They did sound nice at full throttle however, but how often does one go full throttle in the USA, not much. But this is only my experience, if you like it and it makes you feel the car is running better then have fun.

Ill get my good camera out this weekend and take some good pics of the intake off the left side and look up the part#s.
what i used that you dont see is the flex tubing running from the spectre coupler (that is connected to 90* chrome piece) to another rubber coupler that is open beside the radiator. so its actually getting air from 3 places now the 2 stock intake holes and the one i made left of radiator

ok here is the part#s
8147-piece that is connected to end of air filter(i used CF from dash to cover this)
8708-this is 4in straight piece
8706- chrome collar to connect pieces need 2 of them
8701-mounting kit i used 2 of these the 2nd i used at the first collar near the filter end to keep everything tight and not move
8698-90 degree tube
8771-black rubber piece with spectre printed on it
8741-black flex tube not seen
Ok now for what you cant see or know till you start working on this mod
that piece at end of filter is a ugly beige color i wrapped with CF i used on dash. it doesnt fit firm to filter but if you use 2nd bracket kit will make it very frim. you should have the collars you need to connect everything with out buying them extra. you only need about 1/4 of the flex tube to run out the front. i used the rubber piece that comes with flex tube on end where it is open beside the radiator. you will have to cut this with an xacto knife once it is connected when done it should be a tad bit bigger than the stock intake ports. you will need a bracket to mount black box(look at purple zip tie in my pic) i used a piece of real CF. i used 2 black hex bolts to replace the stock silver bolts. handle the rubber peice with SPECTRE printed on it carefully it comes of easily. i also painted bracket used on collar at end of filter to keep from standing out
hope this helps ill try to get better pics this weekend kids been sick and didnt get any yet

P.S. Drilling holes in the muffler is an awesome idea, no idea why I didn't think of that sooner.

Your correct the X Type for a passenger car has a well thought out intake system. I don't see how a CAI could pick up any more cold air. I use a K&N myself and have for many, many years in my car and for street driving they do the job.

Yes without a heat shield in back of the filter, you are kinda defeating the whole purpose of a COLD air intake. All the one I fooled with had heat shields of some sort.
As someone and I said the intake in these cars are about as good as your going to get as far as cool air intake. Years ago a friend of mine took Dynamat
and wrapped his air box and most of the intake pipe with another flexible heat repelling material, didn't do much. I still say a replacement K&N filter will produce the same results. Dyno the car and see how much HP you have gained, if it is more than 5HP I will be surprised. If you had a supercharger or turbo charger, then there might be some gain in HP and torque and noise.

If you are purely into augmenting performance, don't modify your X-Type with anything cosmetically appealing.
If performance is what you are after, strip it of its interior, replace glass with lexan wherever possible, have carbon fiber replacements made for the hood, fenders and trunklid, take out the AC compressor and other non-essential engine components, move the battery to the trunk, get some forged 16 or 17" wheels with track tires. The end result will look ugly, but should get you around a track faster than stock.

Face it, we're driving a semi sport semi luxury car. I'm adding the CAI (actually HAI) simply because it looks cool. I would have gone with an M3 or an AMG if I was looking for dazzling performance.
