Buy Oil Filters

Adding or changing the oil isn't enough to keep your car running at its peak. It's important to change the oil filter each time you replace your motor oil. The nylon or metal core of oil filters is engineered with a filtration system that captures engine system debris as small as 30 microns. A nylon core is one and a half times stronger than filters with metal cores. Ask us at Merle's Automotive Supply about the nylon core oil filters we have in stock.

Change Your Spark Plugs

No matter how you drive, or what you drive, a vehicle's engine demands a relentlessly durable spark plug. Spark plugs vary in price based on the material and engineering. Copper spark plugs have a copper wire tip and are the least expensive. Copper spark plugs offer greater cooling but wear down more easily than platinum spark plugs. Conversely, platinum spark plugs cost a little more but last a very long time and fire hotter. The highest cost spark plug has an Iridium tip and is six times harder and eight times stronger than platinum. Iridium has a significantly higher melting point. While they may cost more, Iridium spark plugs are well worth the investment. Most spark plugs offer limited warranty coverage.
