Increase FE with warm air intake
Hello,
Ive had the idea burning in my head for weeks now. Durning the winter, my personal MPG has gone down significantly. Although, most people cant wait till winter because it increases preformance. But since, with the more dense air, more fuel is required to maintain the ratio, there should be a way to prevent this.
What if one were to put fins on their catalytic converter, a circumscribed rigid air duct over them and the exhaust line to the engine bay, come off of the exhaust line, and go into the air filter box.
Of course there would need to be a servo controlled damper on the normal air inlet, as air would want to flow from the area with the least resistance. This would also allow air to bypass the heater and allow cool air in when the cat gets too cold or the driver wants more performance.
I will try it soon,
but let me know what you think,
Nick
