Just took the truck over to Home Depot. It felt the acceleration from a stop increased. Very noticeable.

I guess with HaHa mod (LOL) the size diameter holes drilled would be up to the person drilling the holes.

 

tried to post a pic.

 

Here it is.

 

doesn't the gotts mod get rid of that piece that you drilled holes in all together?

 

Yes it gets rid of it that peice.
I figured drilling the holes would increase the air being taken in w/o putting a piece of PVC in my truck.

It may help or like I said in my previous post it mentally may help.

 

True a good aftermarket CAI is enclosed but for us poor guys with 97-03 models our only enclosed option is Volant and they tend to melt. Temperature for open CAI's is a big concern because of the dramatic loss in efficiency as intake temps increase. As I stated before from Bill's research, from an efficiency standpoint there is little gain in effective flow in a CAI v. Gott's. The turbulence caused by the flex tube adds little concern because the system can out flow the needs of the engine and once the air enters the heads it is deadened.
The lean problems in the 04-06 5.4L trucks is directly correlated to the change in the MAF location and larger diameter pipe. This is why proper tuning is needed for these and other vehicles that run a CAI.
I don't have the dyno graphs but Bill has shown that the potential in tuning in a CAI v. Gott's is that of a couple hp/tq at most. Is that one or two hp going to make that big of difference given the lower protection of the engine? Well that's for the consumer to decide. When posed with the question what is the best cold air intake?: Gott's has to be tops for the gains, protections, and power/$ spent because the stock intake is already a cold air intake. When posed with the question of what is the best aftermarket CAI?: first I question why they want a aftermarket CAI. Then if they are set on getting aftermarket due to looks, sound, marginal gain, or personal preference, I direct them to a tuner to properly adjust to the modification. After all this, then the best aftermarket CAI can be decided on.

 

I did the Gotts Mod with the K&N air filter and I noticed a difference in acceleration from a stop. I also have a throttle body spacer to make the air into the throttle body more uniform. I got an 1 MPG increase by doing this. May not be much, but a little bit goes a long way nowadays with high fuel cost. Thinking about removing the tube from the air box to the throttle body so I can get rid off that bladder that's on there.

 

Airaid Intake paired with a 50 Series Flowmaster single exit exhaust, and it sounds pretty sweet...can really hear the air being inhaled into the engine...deeper tone too.

 

Pepboys got the whole system for less then 150$

 

I just bought an '02, 4.6L 2wd with under 40k miles on it and am interested in getting a dry CAI. Does anyone have any experience with this particular engine? I am looking for power and maybe some MPG improvement. Recommendation?
