Rep Power: 0

I have some time off during summer break and I wanted to do some upgrades on my Hyundai Elantra. Anything I should start off with? I'm really new to cars,being a girl and all I really don't know too much but I'm a great do it yourselfer.

So whats something easy to start off with? A friend of mine said I should buy spark plugs to increase the horsepower. Personally and logically I don't see this making too much of a difference seeing that the engine is pure factory.

Anyways, I appreciate any input.

... spark plugs wont increase hp... sell it... putting money into a hyundai is a waste
