DIY - Air Box Mod

I won't even start a flame war on the difference, before and after, on the Butt Dyno, but I can assure you the top end sound has unexplainably improved tremendously!
Man I love this truck!!!

A question about your signature:

The 15.34 and 95.0 mph do not seem to match up. Typical trap mph for that time would be more like 90. I would think you would have to get seriously down into the 14's to get a 95 mph trap speed. Is there a typo there? I realize you have some mods that might get you down to 15.0 or even 14.9 with the right track conditions, but mph would still only be maybe 91-12 or so. And those 22 inch wheels are real speed and time killers.

Could you please explain?

No whine before or after for me, either.

I never did hear the Waaaaaaaaaaaaaa, either. and now, with the magnaflow muffler, all I hear is the exhaust, and I love it.

Snorkle mod, K&N filter and 12256 Magnaflow is the cheapest way to get close to CAI and full exhaust. under $200 if you shop around. Big, big difference. sounds great and feels great. Oh, and the 2 degree advance. I am exceedingly pleased.

As to why Nissan doesn't do these simple things - I'm sure it is the noise. Definitely a head-turner. Even the guys up at my dealer were impressed when I told them how cheap this could be done. A couple of the techs are now friends, and do my consult work free - couldn't be better.

If you live near Blue Springs, MO, and need the 2 degree advance - PM me and I'll try to get you in free...

Thanks, guys, for all your suggestions. Saved me big money!!!

ITS A LOUD GROWL and its raspy!

I had a spare 10 minutes yesterday afternoon and did this mod. I've driven around all day today and I don't think it did too much as for hp or lbs. But it does sound mean, kinda like a nascar motor. I have the Magnaflow cat back and a K&N dropin. If you like the growl this is a no brainer mod.

i did the red hot knife trick and it worked well othere that when i slid the knife strait down the snorkel i got to close to the edge of the box and cut off the lower snorkel tab. but its still in there solid as a rock i still couldnt get it out w/ one tab. i cant tell if there is an increase in power yet. ill have to race my buddies tundra to tell. it does give a mean sound though. i wish the groan of the intake was a little deeper though. not bad or a free mod.

haha my head hurts from reading all these posts, determining weather or not i am gunna hack away my snorkel, and I came to the conclusion that aggie is one smart cookie.... Tomm. after work, that ****s gone! ahaha

I did ECU resets after the muffler. But, shailey says he doesn't ever do one. Guess the ECU will learn the new setup eventually whichever way you go. But, I had SES light on WOT, and the reset took care of it. When I went to the dealer the next day for a TPMS reset, there were no codes at all.

Well I just finished doing this mod and testing it. I can't really feel much of any difference, but it sure sounds cool at anything over 3k rpm. Best 0$ I ever spent. Well, actually it cost me $35 since I bought the K&N drop in.

Just did the mod... sounds so nice! I cant wait to open her up on the freeway... Damn this is gonna cost me a lot in gas the next few weeks...

4x4aggie - your analysis is cool. so let me ask you, do you think its a good idea to do this? will it increase HP?

LOL - my last tank, I'm up to 10 mpg -- too much fun!!!

harbrown -- don't forget a good, high-flow air filter. and 2-degree timing advance. I definitely notice the difference -- my foot is twice as heavy!!! LOL!!!

I'm afraid I'm not going to get much more till an UpRev tune. An Injen may make some difference, and I could do full exhaust instead of just the Magnaflow muffler, but I can feel flat spots off line under WOT. So, I think I am ECU limited right now -- but that is better than being intake / exhaust limited, IMO.

There seems to be an increase in performance. I love it. Now I gotta get that filter... only 2k miles on my truck and the factory filter looked burnt in that corner ewwwwwwwww

[TitanUp2004]

Thanx For the info on the Air Box Mod Aggie. Did notice a little difference. Little better throttle responce. Thanx

Went out today with my propane torch and an old Ginsu utility knive, and cleaned up my mod (it was messy and incomplete from using a jig saw). sooooo easy. in place. took five minutes to cut a nice, curved cut from about 1/2" from box at top to about 1/8" inside of tab at bottom. Definitely the way to go...

Can someone confirm.... to reset the ecu, all I have to do is unplug my battery for 10 hours and then hook it back it up? I thought there was some sequence of steps to do it.
