    COOL So did you have good results with your WAI so far?

    It's too early to tell. I haven't put enough miles on the car to see any results. I need to know how much fuel it's using, and that I won't know until I gas up again.

    Warm air also is more prone to detonation, hurts power and pick up, and can have adverse effects on engine life. I could see something like this durring the winter but I don't like the idea of using one in the summer. Warmer air requires less fuel to burn but your also lossing some of your flexibility of the ECU to do what it does. You lose timing with hotter air and that has its own effects on fuel economy and the MiVEC system which is always trying to reduce fuel consumption. Your also lossing the EGR system which does the same thing but better and without killing your power and pick up.

    There are good and bass to everything... I personally am not too big on the wai thing as I feel that's more of a marketing gimic then anything. But that's just me.

    I took a trip with the warm air intake and insulation on, then one with them off the engine to get some mpg numbers, then I put it back on and took another trip. Here's what I got:

    Trip A - Insulated WAI, insulated snout & airbox, ambient temps 10-20s F, IATs ~145-160 F, 209 miles, 4.394 gallons of fuel - 47.6 mpg

    Trip B - stock intake, ambient temps in 10-20s F, IATs 40-60 F, 216 miles, 4.745 gallons of fuel - 45.5 mpg

    Trip C - Insulated WAI, insulated snout & airbox, ambient temps 9-12 F, IATs ~118 F, 155 miles, 3.216 gallons of fuel - 48.2 mpg

    Well. Hot air makes less power then cold air does. I do not see the whole idea of a "warm air" intake, Your decreasing power. Unless of course that was the idea

    Last February I ran the warm air intake back to the exhaust manifold shield with 3 inch dryer duct, covered in duct insulation. My intake temperatures are consistently 100 degrees F above ambient temps, with most of my grille blocked. Other mods are back seat and antenna removed, and smooth wheel covers. My MPGs are consistently in the upper 50s. If you are interested in faster engine warm ups and higher MPGs (not more power), you could consider a warm air intake. All my mods are listed in my fuel log and in my garage.

    Did you run this set up through the summer as well? If so, any issues?

    Yes, I have been running it all year. I use a scanguage to monitor intake air temperature and coolant temperature. In summer I open up the grille block some to let more cooling air to the radiator, which changes the airflow through the engine compartment. If intake temps get too high, I can easily move the aluminum dryer duct off the exhaust heat shield. It's not attached to anything back there, just sitting on the shield. I just lift the end of the duct off the shield, and it lets cooler air in. No tools involved.

    I haven't had any issues like pinging, overheating or not enough power.

    Winter mileage definitely suffers with the cold weather so the WAI might be a good chance to counteract that loss.


    Will weld for beer.
