So while I’m very happy with my car, it doesn’t perform very well in the wintertime when the temp drops. So a lot of people have done a mod that redirects the air intake over to the catalytic converter in order to suckup the radiant heat that it gives off. Rather than the traditional air intake with is in front of the car.
Originally I had thought about doing this using a 12v car heater and a temp sensor to keep everything stock, but this way (while kinda cobbled together) should be an interesting test. All it cost was 6 bucks and if it helps me get the car over 50mpg I’ll be pretty happy.
So here’s a pic of what the engine compartment looks like generally:
And here’s the tubing I picked up from a local autozone:
After some careful bending and stretching to expand the tube fully (I only got about 32″ out of it….supposed to be 36″) I routed it under and around the battery cage avoiding the transmission assembley:
And here’s where you can see it terminate at the catalytic converter:
Pretty simple, all I did extra was use a zip tie to hold the end by the cat. Once the engine is warm the converter should put out a fair amount of heat which should improve the performance of the enigne….I guess we’ll see.
