Did 2 new fuel economy mods

One is a WAI and the other is a tube from the WAI to the header to make the air hotter and make the air sensor make the ecu make the engine go leaner, lol.

Cool.. but I think you're a bit confused on terminology. The tube running from the header to the air intake IS a warm air intake. The big air filter you have (the cone racing filter) is actually referred to as a cold air intake.

Actually the big filter is a WAI-Warm air intake because it collects air from the engine bay.

A CAI- Cold air intake collects the air from the fender area where the fog lights are.

Sorry, but this is an Injen WAI, you can even check it out online.

My mileage is already improving. I installed this after 200 miles of my current tank. I'm at 275 miles and I still haven't hit the 1/4 mark. I'm prediction a 28-29mpg tank. My next tank should be in the 29-30's. My car idles at a lower rpm and seems to heat up faster.

Sorry for the bad picture quality, it was taken with a cell phone.

Is that 3rd fill-up a misprint? 50 miles divided by .341 gallons comes up to 146.6 mpg. I'm jealous!:-)

No, it's not a misprint. I went inside the gas station and started complaining. They said the pump never lies. So I proceeded to show them my car and they went ROFL.

I wonder if the pump screwed up and it should have read 1.341 instead. Either way, it's pretty good mileage.

I did some further tests

I did some further tests tonight. The way the WAI comes for my car is a huge tube and a filter, which killed my low end. What i did with the mod is just replace the filter with this one and kept the original hoses going to the TB. And obviously added the pipe going from the header to the WAI(cone filter)

Before when I used to accelarate in 4th on the freeway it would always downshift, but now when I accelarate it accelarates in 4th. All that happens is you hear this shhhooooooooooooooo noise from the intake and it accelarates. Don't confuse the shhhhhhhhhoooooo noise with the WAI screaming. Now when you put the pedal to the metal it downshifts and the WAI screams.

Also for the street I noticed I have more power in the low end and it accelarates a little faster. If you think this is a butt dyno then you're wrong. I've tested this on the track and it improved my times.

I still keep running into the same damn problem, when I go WOT in 3rd gear it accelarates really slow at 4k. Even with stock it did it. I think it runs pig rich in that rpm and is killing power.

3rd fillup

More likely that the gas in your tank expanded a little from heating in the 50 miles of driving. Not a very accurate measurement!
