Here are a couple pics that I took when I did mine that may help everyone out with the grinding part.

I took a piece of paper and traced the hole in the fender and cut it out on the line


Then I compared the template to the rubber piece that goes into the fender to make sure it was close


Next I traced the outline onto the end of the pvc pipe


I used my Dewalt grinder to shape the pipe and found it easiest to use a ratchet strap to hold the pipe tight to a bench so I can just spin the pipe as needed. Just ground the pipe till my line was gone and tried it, fit the first time too

 

For some reason I had to take tons more material off with mine. I should have broken out the grinder to make it go faster.

 

Is there any possible way to modify the stock intake tract so I can remove the part with the stupid mufflers? I know I could just get a pipe to go in but it's an odd shape.

 

Hey.

Ya could, but it's been shown to not be necessary as the effect on flow is very, very minor, and they still offer to keep any potential unwanted drone at an absolute minimum.

But it is rather unsightly. Good thing the hood closes

Yeah to be honest I just hate looking at those STUPID silencer thing on the intake. I don't feel like spending money to get a full intake but I wish there was something to about those things.

 

There is but no normal person would use it all the time, trust me, I made one. There are zero gains and with how the filter box is the mod looks silly. Best $40 joke I ever had on those damn rice burners though. I had to spend a week on here to learn how to word things to make it sound serious.

What I made does have some potential but only if I fix the MAF sensor housing.

 

I just did this mod on my 06, and I can feel the better throttle response and power increase on my truck. It took me about 2 hours. I used white PVC and sanded 3" of it with a grinder to make it fit and once it fit i sanded the whole PVC just a tad bit then put a couple layers of black spray paint on it. Total cost $7!!
It was very worth it.

 

Just did this to my 2006 5.4L. Definitly worth $9

 

I did the same variation the other day and was wondering if the 3" end of the downspout connector actually sticks far enough back into the fender. Sanding down the 3" ABS/PVC pipe seems like it will stick farther into the fender, similar to the OEM reducer that was replaced.

Any thoughts?

 

Here is the latest variation that I am currently running with no problems. Link below:

Just installed this last night. With one of the supplied fittings/sleeves, the Spectre pipe fits very snug in the fender opening. I just hope I worked it far enough into the fender. Thanks again...

 

The connector on the Spectre tubing has about a 1 to 1 1/2 inch flange on it so it should seat far enough into the fender that will allow it to pull the cooler air from there.

OT: I replied back to your grille question.

 

I did this last night. Only cost $2 for a hose clamp. I used some pipe I found laying around the house. I'm all about saving the money man. Anyway it seems to work well. There is a better peddle response on hard accelerations. Seems to pretty much cancel out the power loss from putting 35's on. Good write up

 

i used that spectre tube.. left the coupling that is already attached to one since it fits snug into the fender... then bought the down spout.. perfect fit.. no cutting no hose clamps..

 

And you can return to stock very quickly if you need to.
