Hey people, just got back from afghanistan and bought a jeep patriot. I'm looking for help in areas like spark plugs and spark plug wires, new battery to work well with my bigger 200 watt amp to power my new kicker 8 in sub to replace my boston on, I had put a land n cold air intake on it but it sounded too loud so I put the old factory box back on with a k and n air filter. Really need help with those MPH and horsepower additions if anybody has god info it would save me tons of time and money. Thanks for this site
