| Traced down my numbers thanks to geo9's help. What do I got? not much. 305TBI ,4L60E, 3:42 gears. does have cab lights tho Bought her in May, put on some '05 take offs, reworked the exhaust, MSD ignition, Rancho shocks and helper springs. Savin my wifes' pennies for a crate motor! | |
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) 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.

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) 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.
