cold air intake worth it or not?

Cold air intake's in my opinion are waste of money. Your much better off keeping engine tuned up and any time you replace any ignition parts like plugs, plug wires, distributor cap, and rotor make sure you replace them with quality AC Delco brand parts.

The K&N System Is going to cost you around $200 and for only about 5 HP. This is going to look good at a car show but, not on gas milage. The k&n system has a bad maintance routine also, especially if you dont live in town. The product says it a lifetime filter system but, You have to constently clean the filter and use a special spray to keep it clean. Its my advice not to waste your money unless your making a show or race car.

They are good air filters and do help air flow. Will they give you better mileage and power? Not enough to notice despite their claims of 10-18hp increase. SO if you like the looks and the sound and have the bucks go ahead. If you are looking to get performance improvements, I doubt they are worth the cost.

Not at all worth it. GM designed the optimal intake for your engine, you really think some jerk just lookin to make a buck knows better?
