It's that time of the year again. Your engine has reached 5,000 (or maybe 10,000) kilometers and its time for an oil change. But it isn't just the oil that needs replacement. It's time for a full-blown tune up-spark plugs, ignition wires, air, oil and fuel filters-the works. If you want to save time and money, a tune up kit is best. A kit usually comes with every component that's needed to tune up an engine at a lesser price. It's also put together piece by piece for a specific engine model. A tune up kit is the best option for people who are too busy to shop for individual components. So how do you pick what tune up kit is suited for your engine? Simple. Just take note of your engine specifications-displacement, number of cylinders, carbureted or fuel injected, number of valves per cylinder, etc. Of course, you could cut time spent by simply taking down the engine number. This is usually found on a placard that's riveted somewhere around the engine bay, mostly up against the engine's fire wall. When in doubt, always refer to your vehicle's owner's manual and search for the specifications of your engine, as well as the components that are required for tuning it up. Now that you've got a list of what's needed for an engine tune up, make sure you get a tune up kit that has all those parts. To be certain, order one here at Car Stuff.
