Research on Spark Plugs for Mazda RX8

Has your engine lost its spark? If so, you will surely notice it in a drop in performance, rough running, skipping, or stalling. These indicate that you might have a problem with one of your Mazda RX8's spark plugs. These are regular replacements you should do, and it's a good start to check them for signs of wear every 30,000 miles before your performance is affected. Once you know that you have a problem, restoring your engine's power is as easy as changing the faulty spark plug.

What Do Spark Plugs Do?

The job of spark plugs is to create a spark that will ignite fuel inside your engine. The material the spark plugs are made from determines the heat levels they can withstand, which is important in a fiery chamber. The material also affects longevity of the spark plugs. Your sporty Mazda RX8 will need spark plugs that are designed to support the desired performance. You cannot just install the cheapest spark plugs and hope to get the same performance from them. It's important to find the best plugs for your RX8 to keep your sporty engine peppy.

Best Spark Plugs for RX8

When shopping for Mazda RX-8 spark plugs and wires, you have a lot of choices. Iridium and platinum spark plugs are standard for this higher performing vehicle. These materials last much longer and stand up to much higher temperatures compared to older, cheaper copper spark plugs, but how you drive also affects the life span of your spark plugs. If you drive with a lead foot, you will likely find yourself seeking new spark plugs more frequently, even if you opt for long-lasting iridium. If your Mazda RX8 has an oil leak, nothing will extend the lives of your spark plugs because the hot oil will dramatically shorten their lifespans. If you have an oil leak, get it fixed before replacing your spark plugs to avoid unnecessary damage to the new plugs. Should you wish to take your Mazda to the dealer for your new spark plugs, remember that you will pay both for the spark plugs and for the service technician's time.

Replacement Cost for Mazda RX-8 Spark Plugs

The cost to replace spark plugs on your Mazda depends on the types of plugs you want to install and how much the mechanic or dealer charges per hour. High-quality iridium or platinum spark plugs tend to cost more, but they will make the additional cost worth it through better performance and longer lifespans. The cost for a pair of iridium/platinum 05 Mazda RX-8 spark plugs ranges from $135 to $163. This may not be the exact cost you pay for new spark plugs because you may need more than two spark plugs, have a different model year, or go to a mechanic with higher or lower labor costs than the average. You can still save on your new spark plugs, if your quoted price is more than this range, by shopping online.
