H3 Performance Intake Systems
I have a little more feedback.
I have gone 3 to 4 days at a time without starting my truck in the past 2 weeks. Before the intake, the engine would run a little rough for about 15 minutes or so after the first start. Now when I go for days at a time without driving it, it runs perfectly smooth. Another plus for me.
I don't know if that's because there was some kind of condensation buildup before in that box that isn't there anymore, who knows. All I know is that it runs perfect even after days of sitting there when before it would vibrate and idle rough for a bit.
The other thing is I've now burned through more then a few tanks of gas and I'm VERY pleased with the smoothness of the engine. It's very quiet now and runs very smooth. I know I've said this before, but it seems as if it's gotten better the more I drive it.
The only thing I'm going to do is switch from a K&N to one of the newer dry HP filters. I want to try something new and am sick of the oiling process of the K&N. Does that make me lazy? Probably, but it's what I want.

All good stuff Gunny abd HG.
The ability to select whatever air filter you want for your own truck, and take full advantage of it with an AirDocIntake is what I was trying to accomplish. I wanted to mate a quality application to purchaser flexibility.
I like K&N, but you do not have to use one by any means, lots of good filters out there.
Will be shipping this weekends' purchases tomorrow morning gang. Thanks for your support.

Seriously, I had a load of Aluminized Steel Pipe delivered friday, but with the holiday weekend, and another project that had to be completed, I will be running more tomorrow night. Those then need prep., prime and paint. I let them dry 5 days, so next week we will be shipping again.
However, you sold me out of hosed too, those were ordered last week and should be here soon. Anyone who orders this week after this announcement will be sent an email informing them of a short back order, and I can refund payment if you do not want to wait for shipping.
I had an opportunity to ship a significant product from DETROIT for importto JAPAN, that will be leaving first thing in the morning. I rarely like anything better than selling and shipping a product made here by us to Japan.


Thank you all for your support.
Enjoy your intakes.
Keep Hummerin!
Congrats on your success Jeff! I feel very honored to have been a tester for this product.
My highway engine noise is almost non-existant now. All I hear is road and wind noise. Pretty amazing what an intake can do for your car. Makes me wonder why GM designed it the way they did in the first place
