Cold Air Intake Install (1 Viewer)

[Taylor O]

Got to install my K&N Cold Air Intake today. Couldnt be happier with it. After installing the trail grapplers I experienced a noticeable drop in torque and hp. After this install I've NEVER been happier with the way it drives. The boost in hp and torque is substantial and definitely worth $300 and an hour in the garage.

K&N box and everything laying out.

Here's under the hood with all the crap pulled out

And here is the removed crap

At this point the tube and the heat shield were ready, last thing to do was attach the free flowing air filter

Done

With as much mud and gunk is caked on your motor be careful with that open intake . . .

Does that box seal with the hood down?

 

[yeti in ga]

yea lots of mud caked in there... , I think the deck plate mod and the K&N filter might have given you something close to this but then still able to seal if you get to playing in the mud. But I am sure we all would love to hear the sound of the engine after this mod. Post a quick video ..

They sure sound nice, I miss mine but definitely not the open filter.

Has anyone (independent) ever done a dyno test on a 100 with a cold air intake? They sound great and that can definitely make the truck seem faster... but, I'd love to see some data that supports the HP gain claims... so when I buy one I can tell myself it's for the performance.

the problem is that the K&N isnt as good of a filter as a paper filter; open intakes aren't great for water crossings either

HP is something that really isnt important, especially on such a heavy and unaerodynamic vehicle.

Judging on the amount of mud and crap under the OPs hood, that may be an issue.

Everybody knows stickers give your truck more HP

The one thing I did not like about the CAI, or deck plate was the huge variance in intake temps. One minute it would read 165*F and the next it was back down to 65*F I the freeway. Power also seemed non-existent when the engine was breathing in 165*F air.

i know, i added two this weekend

If you travel off road a lot, which it looks like you do, I would use a K&N pre-filter when you do to reduce the amount of mud, water and dirt that reaches the element. I used one on my last vehicle and I was really surprised to see how much stuff collected on the pre-filter in just a couple of days on the trail.

Some where on one of the Toyota Tacoma forums, there is a thread were a guy did dyno testing for the deck plate mod, CAI and stock box. If I remember correctly deck plate mod actually gained the most HP, then stock box then the CAI actually lost a bit of HP.

Not to jump off the LC topic though but I believe most Japanese cars already tuned/maxed out unless a turbo or supercharger is installed.

I know the S2000 only gained about 15 to 20 HP with 15 grand put in to it through headers, exhaust, intake, high temp thermostat and a tune. Come to find out it all had to do with engine coolant temp and timeing. Same with the G35 guys actually lost HP after installing CAIs...

After putting my 35s on I could barely make it up a hill...it was definitely neccessary

I definitely didn't notice any real performance gains after installing my K&N FIPK, but that doesn't mean I didn't gain (or lose) a horsepower or two. I am pretty surprised Taylor is realizing such significant "seat of the pants" performance gains however. Good for him!

Overall, if I had to do it all over again, I'd probably pass and spend the $225 elsewhere.

I think it's a placebo effect... I think the stock system is effecient and clean.

I have never understood this misnomer "cold air intake". For this to be true, it should bring cold air to the engine. Cold air has more o2 molecules per unit of measure thus yielding hp gains. What it seems like this k&n filter is doing is possibly providing a larger surface area for air to permeate and replacing the air tube with a more straight through design allowing for less turbulent flow. By removing the airbox and replacing it with this cone filter, the air is able to pass more freely, but it is still hotter air than when you have the stock airbox pulling air from the fender area.

Using a scan gauge, my friend recorded temp readings both before and after a snorkel install. The temp readings with the snorkel were lower than without.

That's why doG made snorkels.
