Just bought a winter beater
 

This is my first post, so howdy.
Just bought a 2006 Sierra, SLT 5.3 L ext cab.
I traded my 03 Silverado in, And loving the new truck, had 21 miles on her.
and fully loaded. The only option it doesnt have is OnStar.
I was going to put a K&N filter in it but the dealership said it would muck up the maf.
I've always used K&N. never a problem. are they wrong???
:eek:

Truck listed for 38,600.00 after trade in and emp. discount got it for 28 and change.
