Will new spark plugs = more power
 
Ive got a 2000 Wrangler 2.5L and i need a little more power. I live out in BFE and Im tired of getting past on inclines on the highway cause my jeep only goes 50 in a 55. I know an engine swap is the only way to truly see a great increase in power but in only 18 and thats currently out of the question with my part-time job. Any help for a stupid teenager who thinks he knows it all would be greatly apreciated. Thanks

if the current plugs are so jacked up & worn out that they are causing a loss of power, then sure, new plugs, properly gaped, may return you closer to original power specs.

My plugs had 114,xxx miles on em and I could tell a big difference in power and how much easier it was to crank

With spark plugs, no not really. Some people claim you might see a very slight increase in hp (like 1/2 a HP) with high performance sparks, but I doubt it. This is of course comparing new sparks, if you have old worn out ones then you could possible see an improvement. I'd take it to a shop, make sure the motor is running properly. If you're running larger tires + a lift, this is a common problem with the 2.5L engine.

Wranglers are small but they're heavy bricks..I think curb is around 3600lbs. Toss in an engine that puts out 120hp/140tq and you'll have issues on hills. Keep it tuned up and you'll get the most out of her. Gearing lower and reducing unsprung weight would help a lot.
