Heat soak isnt good for the mpg. Downside to doing this with stock air box is air filter gets dirtier quicker, and may end up finding leaves in there.Are there any downsides for this mod? Besides the heatsoak (which is a good thing for mpg right?)
Your all set then. .I don't mind the air filter getting dirtier since i have a reusuable K&N filter
i always thought eco-modders install warm-air intakes...
Most likely you pulling air from the left side of the bumper of where the resonator is. I ran a 3 inch tube from where the resonator is disconnect and connect it to the upper tube where its pulling air from the fender side. Yes is alot louder and im using a k&n drop in filter and it does have a better responseRemoved my resonator yesterday on my 07 FA5 Si. There wasn't much of a sound improvement - it's a little louder but lacks the aggressive hornet's nest fury it had with the resonator attached once VTEC engaged. Throttle response is slightly worse and it seems slightly slower. Putting it back on tomorrow - thanks for the DIY, it was worth a shot!
