Air Box Mod on '03 4x4 2.7 5-speed

Just got my Tacoma a couple weeks ago.
Here is an alternative to the "Deckplate" mod. I didn't want a 4" hole in the front of my airbox for various reasons--dirt, mud, water, moisture (on a windy--rainy--snowy, etc day)--and I didn't want to have to get out and screw in a cover, etc.
BUT--I still wanted to let the engine breathe a little more
SOOOO
I got the K&N filter and a shower stall drain (all plastic) screw on with gaskets.
I cut the hole in the front of the airbox and just screwed the drain in--there are many bonuses to this:
you get better air-flow
you have a built in screen to keep out bugs, rats, mice (you get the picture)
you dont have to seal off anything--the built in rubber gasket comes with it
the part of the drain that sticks into the air box is tilted forward and has rings inside it--SO if any water, mud, etc does get that far--it should catch on the rings (somewhat) and drain out the front
IF you ever want to close it off completely the make a drain cover that snaps right on!
Cost me $11 at Lowes and took about 20 minutes.
I haven'd had a chance to measure the actual gas mileage gain--but I really do have a better throttle response and it actually will gain speed on the hill above my house now in 5th gear!

Just an FYI--I like it better than the deckplate mod--for simplicity, etc.

 

good job man. good and innovative!!!

 

Thanks!

I am interested in any possible mpg gains--I should know by next week!

 

First check of MPG gains--about 2.7!

 

Just got introduced to the air box mod on Tacomas. I've removed factory snorkels on previous vehicle and felt a nice improvement in throttle response. I was looking for an alternative to the snorkel removal and like this concept and especially since I'll leave the off-roading to my jeep.

Thanks for sharing this.

 

These trucks really do behave better when you free up the airbox! Nice idea you have there OP
