I own a 97 Silverado 4x4 with the 305 Vortec. Can you remove the cover that is over the stock air filter and get more air through it. Would this help increase hp. It's not going to be much hp but not wanting to spend money right now on a K&N setup or whatever else is out there. I am new at this so whatever info you can give me will help. Thanks :bowtie:
