Breath of cold air.
Thomarus. Keep to the simple forumula more air, more fuel and greater spark is the key fundamentals. So yeah a cheap and one of the first things you should do is a cold air system. A K & N filter panel filter i recomend (in standard air box). This flows reallly well with use with vs s.c air induction over radiatior or do what ive done and make a cold air indction system under car. Do not use a pod air rampod style the commodore engine bay retains 2 much heat from the radiator and enigine etc but all personal choice... The stock air box flows better, this has been tested. K & N, Redline, Uni Filter or simlar brands should set you bak $80 - $120, i piked up my K & N vn v6 one for $100 . Also the best thing along with the engine breathing well the filters can be cleaned, have great usage and ull never need to buy another cheap paper filter again. Cheers Subdue
