2011 K&N High-Flow Intake Install 4.0L

Sorry all - I'm going to take this Install of the K&N to another Thread - again I'm new and trying to get this to work.

1. STEP ONE: Lay everything out on the Garage Floor

This is the picture of the K&N complete kit that I purchased at Chuxs Trucks in Olathe, KS. It cost me $279.99. I may have been able to get the package online cheaper, but I like to buy locally to support the local business here in town. The Kit number from K&N is "

$300 63-9025 K&N Cold Air Intake System: High-Flow Air Filter, Increase Performance & Towing: Compatible with 2005-2011 TOYOTA: Tacoma, 63-9025

63-9025" - it's called the "Toyota 2005 - 10 Tacoma V6-4.0L AIRCharger High-Flow Intake Kit.

The instructions supplied by K&N good but the pictures are "tiny"... no kidding. I literally had to get a magnifying glass out to try and see better so I could get a better understanding of what needed to get done for some steps - they are of poor quality in black & white. Really - they could have spent another 50 cents and made a much better copy of the instructions for everyone. Note - they haven't updated the instructions since 2010 and I found it to be roughly 95% correct for the 2011 Tacoma, but maybe there were a few changes in 2011 that weren't updated in the instructions or they just didn't bother to update it - I don't know. So here goes my thread on how to install the K&N kit... by the way it's worth it! Get ready for a "waaaa" sound when you push on the accelerator - it is definitely louder.

The picture below is the kit open'd up on my garage floor.



2. VIEW of Engine before any changes:

This is a straight shot of the engine before any changes.





3. Another view of the kit - this time it's with the package of nuts / bolts and other items open for a clearer view
As you can see there aren't that many parts and in reality this install is NOT that complicated. Plan on taking 2 hours to take your time and doing it right. I will try and highlight through these step-by-step instructions which parts were confusing to help everyone and what to look out for in parts that may be "not so obvious" for the beginners (like me).


4. Initial disassembly - not so scary
The REAL 1st step is to takeoff the Engine cover. it's quite simple, just unscrew 2 nuts off the top and and "unhinge" it from the back. It just comes off. There is zero danger here of screwing anything up. Below is a copy of the Engine Cover laying on my garage floor upside down.






5. Loosen the hose clamps holding the "air box" - the resonator is attached in the 2011
Just use a screw driver and loosen the hose clamps (see clamp with blue plastic below) so you will be able to remove the hose in later steps. Again - nothing dangerous here.



5. Idea here is to get the air box assembly, hose removed

I have several shots below to help get you acclimated to the hose that must be removed, mass air wire harness, etc. Essentially push in the clips on the crank case vent hose - just push in the clips with your fingers. Very simple and pull, it comes right off. Leave it for now.

If you look at the picture below of the mass air wire harness, its simple to remove also. All you have to do is "push" in the clips on each side of the wire-clip, pull and it comes right off. Again just let it hang.

Now here is where the instructions differed from my "learned" process. There were two little plastic "ties" that held the mass air wire harness to parts of the engine. I tried like crazy to see if there was a way to push something or jiggle the plastic ties so it would let the mass-air harness come free. But to NO luck. Thus on to plan "B" - which is I simply took a sharp knife and cut them free. In the end it made zero difference. So this was the only part of the process that I was concerned about - but in the end it makes no difference. After you have cut free (2 plastic ties) the mass-air wires they should hang free from the air box assembly (the original part the mass-air clip was attached to.










5. Remove the air hose

This is another easy part. Reach into the air-hose that is attached to the air box assembly. As a new owner I cringed a bit here I have to admit, I pulled "straight" out - that is grab the air hose and pull straight out from the wall of the truck. There is a sort of glued foam part that is attached to a hole in the truck wall. It comes out, but will take a bit pull. It comes out clean. See pictures below.

 

Did you ever finish posting (2011 K&N High-Flow Intake Install 4.0L). I bought one and could use some better Instructions than the ones that come with the kit. You are right the photos are too small. I have a 2011Tacoma. Any help would be great. Dave

 

Wish u finished this... Can't find the rest anywhere. Good beginning though. Lol.

 

I installed this on mine, pretty easy. Maybe i can answers your ???

 

this is where i got stuck at... "Remove fuel pressure regulator hose from back
