Cold Air intake for 1992 Formula 350
Hello All,
I just purchased a 92 Formula 350 and want a cold air intake. I can't find one online anywhere. Are these like unicorns? Any help would be helpful

You can look for SLP CAI used. I'm putting one on with my build this weekend

Used SLP air box is the best bet.

Re: Cold Air intake for 1992 Formula 350
I am in the same predicament that you are. I recently purchased a 1987 Formula and have been working a solution in my head.
Take a look in the engine compartment and you will see only one possible way to get cold air without modifying the car (ie. relocating the battery). That is by some system that goes through the front passenger side fender and then down into outside air. Search some posts for the SLP air box and that will give you a good start.
Funny...now that I am typing this I remember what I did when I had my 1991 Formula so many years ago. I used dryer tubing that I duct taped to the air inlet and routed through the fender. Then I attached an aluminum dryer vent to the bottom of the nose. Crude but effective.

Re: Cold Air intake for 1992 Formula 350
Thank you everyone for all the reply’s. I actually found one from EBay. It was about $50 new. It’s being shipped to me and being installed at my shop next week. I’ll keep everyone posted if it’s decent or not. I figured for $50 I can’t lose.

If you use something like this you should fabricate a barrier between the filter and the rest of the engine bay, like modern day CAIs

Re: Cold Air intake for 1992 Formula 350
I have an air filter hanging above an empty battery tray. Air temps are pretty much whatever is ambient as long as the car is moving. There is a fresh air supply from in front of radiator, up through the fender, and onto the air filter. Obviously when you come to a stop the inlet air temps will rise due to engine bay heat.
When I go to the drag strip the air temps will go high while idling, and then drop when I do the burnout. I'm not even moving during the burnout. Just the big suck of 7.0L of engine is enough to move fresh air into the engine bay.
So I think the benefit of boxing the air filter isn't so much about reducing air temps, but more about using it to foster a ram air effect. In other words, you need more than just the box to make it worthwhile.
