Hi Jack. I didnt think that removing it would gain me much other than getting rid of something goofy looking under the hood. Thats why I was only planning on doing it if the Gotts mod worked so I woulndt be altering a factory intake I may want to put back on someday when I change vehicles (long way off though). Thats also why I was going to tape over the holes from the inside first to see if it would change the sound too much. By what you've written though, it sounds like the silencing comes not only from the air passage through the unit but also from having something large and springy attached to the main intake tube. So maybe I'll just leave it alone for the time being. I've been driving around with the Gotts a little bit now and it seems to be just as zippy feeling as the S&B but driving the same routes and with just as gentle a foot as I was using before it doesnt seem like I am getting the same fuel ecomomy with it as with the S&B. I was averaging just over 19 MPG with the S&B and Im getting just under 18 with the Gotts. I realize a lot of things can affect this so I'm not jumping to any conclusions yet, just my initial impression.

Thanks for everything

Joe

Interesting feedback, Joe. I'm reasonably certain I gained about 0.5 mpg in highway driving with the Gotts mod. But, as you say, there are MANY factors that effect this, and one tank of gas isn't really a fair test. I came up with my 0.5 figure comparing two trips of about 1,000 miles, but even that has variables that could alter the results.

I DO know that those of us here that are "close" to PHP are firm believers in the Gotts mod. It is certainly possible that a correctly designed commercial intake could beat it performance wise, but the difference would be minimal and would hardly justify the additional expense. I agree though, the commercial CAIs look kind of "cool".

Well, I've decided to keep the Gotts, 400 bucks for something only slightly better just isnt worth it. I'm going to put a k&n filter in place of the paper one but thats about it. The major reason I'm doing anything to this truck is for fuel economy thats how I'm justifying it anyway. A ten dollar mod has a much better return on investment than a 400 dollar one. Next project is a flex a lite monster fan. I got most of it installed this afternoon. Just have to hook up all the wires in the morning and them im in business.

Yep, if you gain JUST 1 average mpg it will probably be paid for after about 4 tanks.
