K&N has gotten the most negative reviews on this board. But there are people who are happy with it.

I know Outlaw, and Brute Force are praised highly on this board.

 

And that one company that I can't think of, who uses the stock air box, but uses their "foam" drop in filter, and just adds a new more effective tube, to the throttle body, looks to be the best in my opinion.

After a great deal of research, I added the True Flow to my 02 Yukon XL 5.3L. You are correct in that it uses the factory air box but replaces the filter with a their foam element and a really nice metal tube. The entire unit is very high quality and fits just as they say it will. You will notice a little "intake music" at full throttle but other than that, it sounds like the factory unit. I have tested my first 3 tanks of gas and as of today, it has increased my mpg by a solid 1 MPG and best of all, you can actually feel the difference beginning around 2500RPM all the way up.

 

I would encourage you to go to their website and take a look. They have a great video on the site that does an excellent job telling their story.

 

Bottom line, it is a great looking piece that does exactly what they say it will.

      2019+ Brake failure, it's complicated

      By needafix · Posted

      I'm not sure if this should be a new topic, let me know if it's out of place. This my first post. Thanks 85077522 - AC Delco GM Genuine Parts Brake Master Cylinders. Anyone else had to replace this brake master cylinder yet. I didn't do any brake work, it looks like new parts and I've had the truck for about 4k miles, 119k total miles.  When it started to throw codes I did the calibrations with a bidirectional scanner and got the codes to clear but they came back so I did the routine; base bleed, automated bleed and final base bleed. All that with Bosch ES16-32N fluid (please look it up). That seemed to fix it but 100ish miles later it failed again so I ran the same process but with a pressure bleeder this time and got the same results, fixed for 100ish miles. The original fluid looked bad and I thought I got most of it out, it could've been the wrong fluid. The codes; P25A2, C05B0-00, C2A1B. I can get them to clear but not for long. The C05B0 indicates a leak in the front circuit (which is bone dry) so I'm thinking of doing the bleed process on that front again today and I don't know if that's taboo to just do the front but at this point it seems like it's worth the try anyway. The new master cylinder/module unit is supposed to get here today. But now I'm pretty much convinced this install is over my head. I've called several shops and some mobile guys that I know but this thing is like radio active material, scary wise. I did get 2 local shops say they should be able to do it, one says he has the SPS2 programing capability. And with the battery disconnected is there supposed to be pedal resistance, mine is to the floor, then if I pump it I can get some resistance. I had a panic stop prior to this issue which may have contributed from what I read. And on the first attempt to bleed and hydraulic test the scanner listed things to look for and one was any gaps between the pad and rotors which I did notice on the RF corner and I removed the outer pad (where the gap was) cleaned it and the hardware and didn't see a gap after that but will re-check it. I read that if pushing the caliper pistons back then you're supposed to open the bleeder so as to not push fluid backwards into the abs module or it will damage it. If that's true then that's also a possibility from the previous owner having the brakes changed before I got it. I'm using an XTool ip500 scanner. Any suggestions, questions and comments welcome.
