want to convert fogs into intake vents

hey everyone, i have a 93 mazda mx-6 and i was thinking about converting the factory foglights into an intake for a cold air system. Anyone have any ideas about how to do this or what im going to need. Anyone ever done anything like this? Would you use fiberglass or abs or ????. Thanks for input.

I wouldnt use fiberglass or ABS. Making tubes with fiberglass is extremely hard...bend ABS is very hard as well.

Find a company that does mandrel bending, use steel tubing instead.

Good idea lad , I did the same for intake , used my fog light ports added a oversized intake tube on the vent (inside the bumper) used tin pipe to direct the air in as straight a line to the filter as possable and sealed the air filter box to make the ram air work like a ram air induction at higher speeds , works really well and costed me 10 bucks.
In your case the fog vents are wide not circular , a heater vent from a house should fit around the inside of the fog vent and bent and molded to a tight fit , use screws to hold it in place , then use tin pipe routed through the fender to the air box , port the box so the tube will fit in and seal it. There you go you have ram air and it shouldnt cost more then 10 bucks.

yep. This idea has been popular for Mustang folk for awhile. Or atleast the idea in general. But, its kinda usless sending in THAT MUCH air into your engine, with a stock MAFS, unless you upgrade that too. BTW, PVC and Duct Tape. :D

I would recomend pvc, it bends well with a heat gun. Use fiberglass or construction adhersive to seal it to the back of the bumper. No need to upgrade the airflow sensor, because hes not going to be sending more air into the motor (well not enough to be considerable), its more for the cold air effect in witch the air is more dence, meaning more fuel, meaning more power.

ok sweet!
what do you use to heat pvc?-heat gun?
thanks for the advice everyone!

I have all my intakes ported including the mas , bored it out to 3'' or 75mm it was less than 55mm before. I basicaly turned a gm mas into a ford style mas works great with ram air.

yeah, it bends quiet easy with a heat gun. You can buy one at most hardware stores for around $20. Wagner makes a duel temp (750 1000) that I baught not long ago for 20 (USD) and it works really good.

i have a sweet idea for a major ram air induction for any vehicle. It requires a airdamn with a big port right in the middle ( where you would normaly put a grille, which will still be there either way ) and you can use the ducting from like a house ( right where the vents come out from the floor, you know, for heat ) and place it right behind the big vent and run your choise of tubbing from the vent up to you intake or filter... you would gather a lot of good air from there.

Using PVC is about the stupidest idea i have ever heard.... the gray UV resistant PVC may work but your regular white PVC will become so brittle over time and at first if exposed to any heat over 120 degress Farenhight will begin to get "mushy" and release gasses that are going to murder your engines power....Aluminum tubeing would be #1 best idea but the most practical is stainless exaust tubeing...most automotive stores have pret-bent parts and they can be either welded togather or you can use rubber clamps....

you might want to learn how to use the quote feature so you dont look like you're repeating what someone has done said. As for your stament your quiet wrong. Schedule 80 pvc can withstand over 300 degrees before gassing out, and pvc will not become brittle for many many years. We all know alumium would be the material of choise but he said he was on a budget.

sorry...im a noob to this board...and if on a budget i would use exaust tubeing long before i would risk screwing my engine up....

sweet :ylsuper: ...thanks

i love these icons/face things...need more like that on AOL...AOHELL...

only problem with bending pvc is it flatens and you loose some inner diameter. pvc has all sizes of elbows at all different types of angles this way your pipe diameter is always wide open and theres no frictional loss of air flow.
