Spark Plugs

The least expensive part in your automobile engine is also one of the most important part – The Spark Plug! Many manufacturers are now claiming many crazy miles between spark plug changes but the reality is that few cars can last that long. This is a simple maintenance task that can save you may thousands of dollars in fuel costs, major breakdowns and more expensive repairs caused by spark plug neglect.

Installation Guide

1. Only attempt to replace the spark plugs on a cool / cold engine

2. Disconnect the plug connector. If disconnecting multiple cables mark them to ensure correct re-asseembly.

3. Loosen the plugs first and clean the surrounding area to ensure no dirt particles get into the combustion chamber.

4. Remove the used spark plugs. If its too tight, loosen it and pour a little oil / kerosene to lubricate the edges before attempting to remove again.

5. Check gap of new spark plugs and adjust if necessary. (check with your local garage or manufacturer handbook.)

6. Thread in the new spark plug by hand until tight. Using a torque wrench and suitable spark plug socket, tighten the spark plug according to the torque guidelines chart below. If a torque wrench is not available, then tighten ¼ of a turn (90 degrees) for gasket type plugs or 15 degrees for tapered seat plugs.

Be careful and avoid overtightening or undertightening as spark plug or engine damage may result. More specifically, if the spark plug does not sit or fit in correctly, you will get a damaged spark plug and will have to repeat the process above. Worse, incorrect spark plug replacement will cause engine damage so please check with someone if you are not confident about replacing the spark plugs yourself.

We stock all kinds of spark plugs but NGK and Bosch spark plugs are the most popular.

Product Review: Precision Hub Assembly

What do our customers say about the Precision Hub Assembly? We asked a sample of the product’s buyers and summarised our findings below:

  • CheapCarPartsdirect.com was less expensive than O’Reilly’s and almost $200 dollars cheaper than auto dealerships.
  • Main symptom:  ABS light kept coming on without warning or reason. Replacing the Hub Assembly solved the problem, even if the problem was not the assembly, but the sensors or bearings built into the assembly.
  • The Hub Assemby was an exact fit and were working fine 6 months following replacement.
  • Cheaper to buy the entire Hub Assembly rather than the ABS sensors or bearings
  • No difference in quality between the parts from our website, and the parts from the local dealerships.
  • All sampled (10 in total) customers would have no hesitation in buying the same product again from our website.

Do it yourself: Change Air Filter

Your air filter needs replacing generally every 50,000 kilometers or 30,000 miles. More frequent replacement would need to occur if you drive in a very dusty area all the time. Your owner’s manual will give you more information specific to your vehicle.

Vehicles need air just as much as they need oil, water and fuel. The filters keep the engine free from dust, insects and all other impurities. Regular cleaning or replacement of the air filter will keep your engine running smoothly. They are not expensive and can be done relatively easily by yourself.

Step 1: Buy the correct replacement filter: Look through our website and pick out the correct replacement air filter for your vehicle. Consult your owner’s manual for help in finding the right part.

Step 2: Open the hood and locate the air filter unit. It is usually situated on top of the engine. Again your owner’s manual will point you in the right direction. Older cars with carburettors have the filter located under a bulky, round plastic / metal cover. Newer fuel-injected cars tend to have a rectangular housing between the front grill and the engine.

Step 3: Remove the air filter: Loosen the clamp that seals the air filter. Undo any screws or wing nuts. Some filters have a quick release system. Once the seal / cover is off, simply lift and remove the round or rectangular air filter.

Step 4: Seal the air conduit with adhesive tape to stop any dirt from getting into the engine during the air filter replacement. Then clean the air filter housing with a vacuum cleaner or compressed air.

Step 5: Simply replace the old filter with the new one. Make sure it fits nicely back into the housing and that all edges are sealed by the rubber trim

Step 6: Replace the cover and make sure that its straight and secure. Make sure all screws are tightened and any / all clamps are in place. Double check to make sure!

Step 7: Shut the hood and dispose off the old air filter in an environmentally safe way.
