Automotive Accessories / Parts FAQ

OEM parts means it is a part made by the same manufacturer as the genuine parts sold at an automotive dealership. Many automotive companies use outside manufacturers to help design and produce the parts used on the vehicle and then the dealer adds their logo and packages it in their custom packaging.

Aftermarket parts on the other hand are produced by a different company than the original manufacturer. While these parts are usually made with the same materials and made to serve the same purpose, they may have slight differences in how they look and feel. Some aftermarket parts, due to redesign, may actually be an improvement on the original. Aftermarket parts are typically much less expensive than OEM parts and usually are of the same quality. The difference is, it will not be made by the same brand as the rest of your parts on your vehicle.

Typically, the difference between aftermarket parts and OEM parts is the cost.

Engine Oil

The principal function of the engine oil lubricant is to extend the life of automotive that operates under different conditions like speed, temperature and pressure.

Sufficient lubricant in automotive reduces friction and removes heat from the engine. At low temperature to maintain the performance of the engine, where at higher temperature to keep the engine apart to minimize engine wear. Regular oil changes have a variety of benefits: they should give your vehicle a longer life, make you engine run smoother, improve your MPG and reduce emissions. So, in the long run this should mean more money in your pocket as your car's day to day functioning is improved and its life time is extended. It may not affect your car insurance rates, but it should cut the cost of servicing and maintenance. So, just by using sufficient engine oil you should make your car healthier and happier.

  • Changing every 5,000 kilometers / 3,000 miles provides maximum possible mileage and performance for your engine and by maintaining clean oil in your vehicle it will help with your vehicles overall upkeep. Research points that this is the good time to inspect the vehicles oil for elements such as dirt/metals, etc.
  • Regular oil change help to extend the life of an engine. Changing your oil will remove harmful contaminants and dirt that have been collected in the oil. The dirtier the oil gets, the more damage it can inflict on your engine.

For many vehicles, look for the American Petroleum Institute's (API) on the bottle.

  • Additive packages play a key role in helping to keep an engine clean and protected from varnish and sludge, as well as provide wear protection and protection from heat and acids.
  • Additives can consist of anti-wear agents, friction modifiers, dispersant, detergents, viscosity index improvers and antioxidants.

The thickness affects how the engine performs. Older cars tend to be worn down, and thin oil will cause more friction between parts. This causes the car to wear out faster than normal.

Thicker oil is better as your car ages, but thick oil can make it harder for your car to cope with cold conditions. It is difficult for a car to warm up with thick oil because the oil tends to move slowly throughout the vehicle.

Spark Plug

  • There is no single answer to this question. As spark plugs grow older, they lose their sharp edges as material from the center and ground electrodes is slowly eroded away. As the gap between these two points grows, the voltage required to bridge the gap increases proportionately. Even the best ignition systems will be strained to supply enough voltage to completely burn the fuel.
  • There are special spark plugs such as premium ones which would last as much as 160.000 kilometers. If you have these, then you should not worry on changing them until you have reached around the 100.000 kilometers, although you should check every 30.000 kilometers.
  • Replacing worn out spark plugs with new ones (with sharp new edges) effectively restores the ignition system's efficiency. Misfires are reduced, power is restored, economy of operation is enhanced and emissions are reduced.

The true test of a Bosch spark plug is found right under the hood of your very own car. It's the same performance and quality proven on racetracks in the world's most sophisticated racing engines. That's why Bosch is one of the best selling spark plugs in the world.

Bosch state-of-the-art R & D centers develop the technology that delivers the performance you expect from a Bosch spark plug. Production takes place in the most sophisticated manufacturing facilities in the world, where Bosch quality control standards assure that every plug bearing the Bosch name earns it.

Wiper Blade

In general, wiper blades should be inspected every six months and replaced as soon as they diminish wet-windshield visibility. Vehicle manufacturers typically recommend replacing blades every 12-18 months.


All mechanics highly recommended changing the oil filter every oil change for maximum engine protection.

Oil goes from the reservoir to the engine passes through the filter first. This means that the primary defense line to the engine's crankshaft, and cam bearings is the oil filter. It's purpose is removing unwanted solid entrants to the system, such as dirt, carbon, and metal particles. These entrants can damage the bearing, journal and cylinder wall surfaces once they reach the engine. The filter absorbs and filtrates against abrasion and premature wear to the engine.

Over time, the filter accumulates dirt that has been trapped, until it reaches a point where it is possible for oil passage to be obstructed. The filter should be changed before it reaches a point where it's an obstruction to the flow of oil, or even facing the danger of becoming plugged.

In conclusion, oil filters cost less than ten dollars, so you may just as well change it with every oil change because the worst case scenario would cost you more on replacing it with a new engine.
