Replying to: hendrix24 (Aug 07, 2005 4:34 pm) I believe there have been problems with the fuel injector system on the diesel engines by GM.

#5123 of 5688 K&N Air Intake System--Worth the $? by m_boise Aug 09, 2005 (12:33 pm)
I have a 2005 Z71 Crew Cab Silvie with the 5.3L V8, added a flowmaster cat-back exhaust and have been looking into the K&N Air Intake systems. Is this going to do anything? I figured since I opened up the back of the system I should open the front also. But I've seen conflicting reports on the value of this. I noticed the Z71 package included a high flow filter. Also, will this mod effect vehicle warranty? I've actually already ordered it, but after doing more research have seen some negative posts on other forums. Should I just resell it once it comes in?

Replying to: m_boise (Aug 09, 2005 12:33 pm) Yep....sell it.....or buy some throttle body cleaner with it.........   How it affects warranty depends on the service manager you deal with. Best to ask him as the answers will vary. Regardless what K&N and Moss Magnuson Act says about aftermarket accessories.....it all comes down to whether the dealership you're working with agrees to it. I would hate to have to go thru a lawsuit to prove a point about an aftermarket air filter.

Replying to: obyone (Aug 09, 2005 5:54 pm) My service dept says it is OK. As far as the throttle body goes, I though K&N was a superior filter...shouldn't this keep the throttle body as clean as the stock intake system, even with the increased flow? Or does the K&N intake system cause some other problem---doesn't fit right? improper installation causing air to enter the throttle body that is not being filtered? Your comments are helpful. Also--a friend mentioned getting a throttle body spacer with helical grooves to cause incoming air to swirl---supposedly causing more efficient burn of fuel, any experience with these? Thanks.

#5126 of 5688 K&N Air Intake System--Worth the $? by m_boise by z71bill Aug 11, 2005 (7:25 am)
The high capacity air cleaner that comes with the Z-71 package (or trailer package) is nothing more than a different air filter. When you go to replace the filter you can pick which one you want - regular of high capacity. If you look at both side by side - unless you have a microscope - you will not be able to see any difference.   K&N is a JOKE - as are all the after market air filter crap that is sold.   The adds claim UP TO 500 additional HP & 65 more miles per gallon - (or whatever)   I have seen guys dyno their cars/trucks - then add a K&N then redo the dyno - NO DIFFERENCE in HP or Torque.   The only thing they do is REDUCE THE WEIGHT (of your wallet)   But wait - they also give your engine a cool sucking sound when you step on the gas. I really think some guys HEAR that sound and really think that they are going faster.

Replying to: m_boise (Aug 11, 2005 6:13 am) Throttle body spacer is also a waste of money.   K&N flows more air. Air that has been filtered thru cotton gauze and oil. It's that oil that makes things a little messy if you apply too much after washing the filter. Course the downside is that if you don't apply enough oil, you will be allowing additional contaminants into your system. Since K&N has no specific amount of oil to add to the filter nor a way to consistently apply it. I'd say you would be taking a risk of having too much or too little and both with consequences.

Replying to: obyone (Aug 11, 2005 8:11 am) Where the K&N DOES have an advantage is after it starts to get dirty it will continue to flow more air than a dirty stock filter. So keep a clean stock filter in. (how to assure that I don't have a clue other than putting a new one in when you probably don't need one yet.) All in all the stock intake is a pretty efficient piece. If you want to improve it you need to get cooler air, not more air.

Replying to: txyank1 (Aug 11, 2005 10:46 am) As you said COOL AIR is what really makes the difference. Unless you supercharge your not gonna get any more air into system by adding a K&N kit over the stock filters. I got the optional increased capacity filter when I ordered my truck and believe it or not I still have the stock filter in place since truck was purchased (57k so far). I thought that little indicator they attach wasn't working after the first 30k miles and pulled filter to look at it and it was same as new just a few bugs. I don't travel in dusty conditons just highway so not collecting anything but bugs.   I can't really say I gained anything with my Borla Cat-Back system either but it sure made the truck sound healthier than that stock exhaust.   Ray T.

#5130 of 5688 what transmission by gmtruckguy Aug 11, 2005 (5:39 pm)
I just bought a 2005 silverado 1500 crew cab with the 5.3L V8. I am not sure how to figure out what transmission I have in it. I have been told they come with either an Allison or some other kind, and I'm guessing the Allison it would come with is the 4L80e. If anyone has any idea how to find out, or what transmission the 5.3L engines generally come with in the 1500's, I'm all ears. Replies to this message: obyone (Aug 11, 2005 8:03 pm)
