Hi everyone. This thread is to show off my new ram air induction set up on my 98 5.0 EL Fairmont Ghia and to urge others to attempt a similar thing. Mine consists of an extra 50mm wide length of tubing running from the front bumper where the cornering lamps are fitted on the NF and NL fairlanes up into my air box. It took about two hours to do without rushing and with all the tools we needed (dremel, orbital sander, power drill, sockets etc etc).
First we removed the airbox, snorkel and all the tubing to the throttle body.
With the wheels turned to the right, we removed the shroud to reveal the underside of the airbox support. Using the length of corrugated tubing which was cut at one end to match the taper of the back side of the front bumper we guestimated the approximate location and area of metal to cut out under the airbox. The metal was removed and smoothed with a dremel attachment.
The bottom of the airbox then required similar treatment. Firstly we fed the tube through the hole and mounted it flush behind the bumper. Then we cut the excess tube off and marked out a matching area on the under side of the airbox. This was drilled out and the tubing pulled through.
The bottom of the airbox itself needed sanding down such that the position of the tube coming up through the plate could be judged.
Then it was a matter of bolting everything back together and hey presto! I must say THE INDUCTION SOUND IS AWESOME! Giving her some gas with the bonnet shut now results in an audible slurp of air… and as for get up and go… well ladies, catch me if you can I can’t wait to get her on the dyno but I’ve got an underdrive pulley kit arriving in a week or so and perhaps some roller rockers before that happens.
A very quick, cheap and easy mod. Thanks again goes to Tibbo!
A much tidier job can be done with a 3" (yours looks like 2" - 2.5") crummydoor intake duct and a rubber coupling from a gas job.
The rubber coupling sits perfectly in between the air box and inner guard, and the bottom can be hose clamped to the crummydoor duct.
Because the duct is 'L' shaped with a nice bend and is smooth on the inside it will flow than the flexi pipe you have used.
This is what I have done to mine. I have to say, induction noise is much the same however. I can't say I noticed any significant power difference either.
You should also seal the intake at the bumper because air will always take the easiest route. That way all the air going through that vent will go into the pipe, instead in the inner guard.
BTW, it is only additional CIA you have done, not 'ram air'.
Rick.

What's that?..... Did I hear you say TQE power?
The price was right= nadda ,, the piping we used 50 mm I/D is the left overs from an LPG install.. It normally covers the wiring and LPG copper lines going to the tank., and is suprisingly thick walled and durable.
3" tubing would not clear the ABS goodies etc under the fender, the last one i did (on a EF GLi) we used 3" pipe but found that it also caused the plastic inner guard to bulge out and rub on the wheel..3" would also only expose the same amount of surface area at the front due to the Fairmont bar insets... You can see in the close up piccies, the piping is nearly as big as the inside opening of the bar insert.
And the noise is greater now,, you can suck a sheet of paper to that cut-out now
tibbo -
I did mine on the XH which appears to have a bigger opening on the bumper, and I also don't have ABS so the 3" pipe fit perfect.
