Best Spark Plugs for Chevy Tahoe

1. Bosch9659 Double Iridium OE Replacement Spark Plug 

These are not just your average spark plugs. Everything from their make to their performance and service life is longer and better. That’s one of the strongest reasons why the Bosch9659 spark plug is extremely famous. Let’s find out what the other reasons are:

• It is made up of iridium instead of copper. The double iridium firing pin, along with the ground electrode inlay, together promise 4 times the service life of an average copper plug.
• The pin has 0.6 mm fine wiring. Through this, you can expect great performance and ignitability. This also reduces the voltage requirement.
• The spark plug also promises durability because it has a 360-degree continuous laser weld that is fused with the iridium plug. When these work in tandem, the result is magical.
• You don’t need to worry about gapping with this particular set of spark plugs.
• The spark plugs have a copper core, which enables better heat transfer.
• Their ribbed insulator design works to prevent flashover completely.
• The manufacturers provide a 7-year satisfaction guarantee, which is extremely commendable.

Best spark plugs for Chevy Tahoe – Buying guide

To make sure that you buy the best spark plugs for your Chevy Tahoe, you should understand how to choose depending on your specific requirements. We have jotted down a few pointer for you to remember:

1. While iridium spark plugs are excellent, and the best choice, if you don’t really want an improvement in performance, you don’t need to buy them. Copper and platinum plugs work well as perfect replacements. 
2. Besides performance, the reason why everyone chooses iridium spark plugs is that they are long-lasting and don’t require replacement for around 100,000 miles. Copper ones are cheaper but they do not last as long.
3. Make sure you buy pre-gapped spark plugs so that you don’t have to worry about gapping them yourself.
4. It is always a good idea to change all spark plugs at once. This is why most products come in sets of 8. If only one spark plug has gone bad, within a short period of time, the rest will as well.
5. You can install spark plugs yourself but if you do not have the experience or expertise to do so, relying on a professional is the safest bet.
