Does K&N make a cold air intake system for the 1996 3.4l t100 4wd? If not, has anyone else had success with other cone & tube models?

 

Seems to me I've seen cone intake systems for 96 and prior T100's on Ebay from time to time. I know there is a K&N filter for the T100 as well. As well, you can do something called the "deckplate mod." This involves cutting an extra hole in your airbox and installing a marine deckplate in the hole. See the following link for info on that mod.1

Deckplate Mod

I personally did the mod to my T100. I figured that if I didn't like the results I could seal up the hole and be done with it. However, I have consistently maintained a 1mpg gain in fuel economy as well as a slightly more aggresive noise from the intake (noise alone wouldn't make me keep the mod however it is just a perk).

Some argue that this is a bad idea because you will be taking in warm engine bay air. However, my experience shows that the increased intake ability outweighs the fact that it is warmer air than the conventional intake built in to the fender. I took fluid dynamics in college, so I understand the principle behind their argument but my experience with the mod has shown the increased quantity of intake is the key.

Hope this helps.

 

I found another mod to help with the intake... the ISR Mod.

However, looking at my intake silencer, I couldn't see that it obstructed intake flow in any way, so I left it alone. I believe 96 and prior T100's have a different ISR than 97 and up (like mine).

I can't offer any experience on this one, but if you read and search you can see others opinions and experience with it.

 

If you want a cold air intake, remove the restrictive "elbow" in the fenderwell.

K&N sucks for 4WD anyway. Go with an Amsoil 115 and either the elbow or the deckplate mod. 5HP right there.

 

Would that work for the 95 T as well? I've got the K&N and a Flowmaster dual out which increased my torque tremendously. Would removing the "elbow" create a problem when I go to smog? Last time, my H20 was 1 point below the mark for passing so I'm thinking I need a new cat anyways because of that and I can smell the rotten eggs while driving but I don't want to push it.

 

Yes it would work. No, it wont do anything to increase emissions.

 

But what about the inspection part? Is it a visable mod?

 

Nope, its in the fenderwell. You would have to be a Toyota freak to notice it.

You have the 3.4 right?

 

Yeah, the 5V motor. So a regular smog guy wouldn't notice but just DON'T take it to the dealer to smog, right?

 

Even at the dealer they would be hard-pressed to see it. Its not very noticeable.

 

And that mod makes an extra 5 hp or is that with the other filter??

 

It will make 5HP, but as with any intake mod, a dirty filter will hamper the performance potential. With an Amsoil or a new Toyota filter, you will get about 5HP.

 

Cool. It sounds great but is there an issue with K&N filters? Why are stock filters better?

 

You can find all the answers to your questions by searching, but, since we are already on a roll, I will tell you.

There is a huge debate about the filtration properties of K&N filters. A group of us, including myself have experienced visible dirt inside the airbox and intake track (post filter) with the K&N. No one that I am aware of has ever experienced this same "dirt" problem with an amsoil filter. Tests have also shown a large increase in oil contaminants while using a K&N filter.

On gadgets site www.gadgetonline.com there are some interesting performance figures for the K&N and Amsoil. Personally, for my needs the Amoil is the way to go. Not only is it about $30 cheaper when compared to a K&N with the foam wrap, it also filters the desert dust here in AZ much better. As for the Toyota filters: When new, these filter just as good as an Amsoil, and yield the same performance gains. Its when they get dirty that the performance decrease is realized. With the Amsoil you can clean it, that is the advantage.
