Product	Description	Avg. Horsepower increase	Installation Difficulty	Avg. Price
Tornado	Rip off...	decreases hp, anything in the way of air is a blockage, so the tornado is a blockage in the intake, not a spherical hp increaser; better gas mileage still in question	0-1 ; depending if you can open the box. lol	$60-$70
K&N Filter (Generation 2)	high flow intake filtering system	up to 27 horsepower increase	3	$200-$300
Gibson exhaust	high flow exhaust system	10-20+ increase in horsepower	5-6	$280-$370
Stant thermostat	lowers engine temp. p.s. any lower than 180 degrees WILL result in damage to engine	not much, but will lower air intake temp. also, so some hp increase will result.	3-5, autozone.com has great diagrams.	$3-$15
MAS air flow sensor upgrade	air flow sensor for efi, Granetali makes a great sensor	some engines increase 5-15 hp	4, not hard at all, 4 bolts, an electrical plug, and one metal clamp	$200-$300
Superchip	Superchip.com, alters timings and fuel/air ratio, plug and go installation.	in some cases, with certain chips, 30+ hp may result, but common increases are between 10-20hp	2-4, use tape to insure stability of install.	$250-$350
