Needs more power

I have a 97 monte carlo z34. It's fun and it's fast but I want my vehicle to have a little more horsepower. what are so options I have that will spice it up without being to expensive. Any comments would be great.

Buy a intake from Ebay. they only go for about $20 and its easy to install. I just got mine and the car runs much smoother now. Also make sure that your spark plugs and wires are in good condition. If they have not been replaced within the last 60,000 miles or close to it you can do that too to boost your HP. If you don't have a dual exhaust system on your car already, you can get it done for about $300. It does not have to be high performance. But pretty much if you get the intake and the dual exhaust system you will have a much better airflow in and out of the car. That alone will boost your hp another 30hp-40hp.
