I'm just wondering if it would be a good idea to replace my stock air filter with a replacement K&N? I know a whole new performance intake system would be good, but I'm really not want to spend $300 on it right now. I wonder if just the little replacement filter would help my mpg or anything? I've read reviews and some say it does improve and some say no noticeable difference. What do ya'll say?

i have had a k&n filter in almost every vehicle i have owned as well as a gm performance intake in my last truck and for the 40-50-bucks it is worth it..F.Y.I..ur truck won't get better gas mileage but it will breath better and accelerate with less effort..just keep th re-oiling to a minimum as too much oil can mess up ur mas air flow sensor.

on another note it is reusable over and over and over ...a little periodic cleaning and it pays for itself over time..JMO

k&ns have their place. they dont seem to work too well on some carbed bikes, on my quad it works great especially on days when i bury it in mud and open the air box and its full of mud with a filthy filter but post filter its still spotless. itll increase the sound a little but chances are any increase in gas milage willbe so minimal you wont notice it. but f it sounds better and you get a bit more pep without loosing gas milage then its worth the swap. ill be doing one after the winter :D

I've been running K&N in my truck for about 10 years. I did get some MAF codes, and the dealer suggested that the K&N oil might be a factor, but in the end, I think it was a bad intake manifold gasket that was the culprit. I don't clean my filter all that often (they say it filters best when it's a little dirty anyway), so I think it's been great.

as long as you dont over oil you should be ok, and make sure its dry before using it. a friends m3 was having some issues with a k&n filter making his car run a little off. we checked the maf and it was wet with filter oil.

I just recently replaced the stock filter from my 08 CC and it looked very clean, after 2.5 years and 22000 miles. If you want better gas mileage drive like grandma, it works. I have recently been trying this and my overal mileage when from 14.5 to 16.5 (hand calculated)....Just take off slower and do the speed limit. BTW, I went with another stock filter not a K&N.

Oh believe me I do drive like Grandpa. My hand calculated average is 18-19. Sometimes 17 if it's been cold or driving on faster highways. I go to the extremes to get good mileage because I drive so much. I just wondered about a new filter. I think I'm going to leave it alone. Mailny because it doesn't sound like I'll detect any difference except in the sound maybe. And I hate waisting money :thumbs:

      Brake Bleed Procedure

      By needafix · Posted

      I'm not sure if this should be a reply on this thread or a new topic, let me know if it's out of place. This my first post. Thanks 85077522 - ACDelco 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. 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. 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 wasn’t commenting on your post. Certainly wasn’t arguing. I was making an observation on my long term experience with supposedly proper length of driving for proper heat cycles. Works for me. Although I have seen water or vapor come out of exhaust when vehicles weren’t run very long and shut off. It’s very humid in the morning. Then hot and humid.

      Not what I said but I can work with it anyway. Complete combustion produces CO2 and H20. When it's cold enough you can 'see' it as water vapor but it is always there and more so the better the tune up. It's physics, not an argument. In a cold motor when the cylinder jacket is below the condensation temperature the water goes to the pan and not the PCV system. Heating the oil moves it from liquid to vapor where it is removed by the PCV system. When and how much depends on temperatures. Of the air, the water and so on. It has little to with the humidity. Water is a combustion product.

      2 speed transfer case optional now?

      By Chuck FB · Posted

      I can only guess as well that something was clicked on that brought you to the half ton choices by accident. By all means try again and chose the 3500 and sort out that its the cab and box configuration you want and choose four wheel drive ( rather obvious to have a transfer case ) and to make sure the dually isn't chosen. I find or at least did a couple of years ago when I was sifting through the options that it would sometimes jump ahead after choosing the series of truck and in this case 3500 and skip some of the other initial configuration choices and have to watch the heading bar and sometimes back up by choosing the first in the series of option break downs. I think sometimes the computer will remember items that were last chosen and skip over the first part. Anyway go through it all and depending on the trim level chosen and I think the LT is one that may fall into that where the option of having the 4 high auto transfer case can be chosen, where as a High Country doesn't show that option as it just comes with the fancier ( not necessarily better though in terms of potential problems ) transfer case but for sure both transfer case choices are equipped with high and low range in the HD truck segment. Like Newdude said who works at a dealership, its the half tons that are the ones that will come with the single speed unless certain options or trim levels are chosen that add the two speed transfer case but as your looking at an HD, you don't have to worry about that hot mess.    One item that at least didn't show up and not sure if it does yet or not in the HD options on the manufactures pubic website is the upfitter in cab switch option if one is desiring that. Unfortunately its not wired in at the factory but the panel with the switches is on the dash but the wiring harness to be installed gets tossed under the rear seat to be installed by whomever after the fact to complete the installation.

      Yesterday we brought home a 6yr  old Havanese dog from a nearby SPCA.  We've had her for 24 hours and we are delighted with how well she is adjusting to her new home.  It  was a huge decision to adopt a dog at this stage in our lives but we believe we made the right choice!   it was reported that her first 6 years were ones of neglect.  I think she's already realizing her life is going to get a whole lot better...  so is ours!
