Love it! Thanks for the invaluable research specs!

In favor for CAI on EFI is that you might get a little more air in than the ECU is predicting for and run a tad leaner, whereas with WAI it can go the other way, you can be too rich without further adjustment. On carbed motors, WAI wins.

However, with modest amounts of either, the difference depends on the driver. The driver without the precision calibrated right foot, will always do better with WAI because it uses less fuel per degree of throttle opening, the driver who modulates his driving technique accordingly, can use less throttle opening with CAI and save gas. Hugely overpowered vehicles with severe "tip-in" will usually always get better improvements with WAI, EFI or not. Marginally powered vehicles may work better with CAI.

These foam sheets would probably make great air dams on top of a grille

You could get a cool texture with this

Aha, I've got some of that stuff, but only in letter size, 12x18" sounds more useful, will have to check some stores to see if I can find it in that size.

I know they have really huge sheets near the Oils, that's where I "hang" out LOL
