How to Choose the Best Spark Plugs For Hyundai Elantra

Well, there are few things you need to look for before buying any spark plug for your car. Here, I bring some of those factors that will help you to get the finest one. 

Types Of Spark Plugs

Different metals are used in the construction of spark plugs. They are copper, platinum, and iridium. The type of metal used can make a massive difference in both performance and fuel economy. Your manufacturer should recommend a specific metal type, but there’s always room to upgrade, isn’t it? Let’s find out their differences at a glance.

Copper: Copper spark plugs are the cheapest and very basic plugs available. They’re known to provide good fuel economy for old model vehicles. 

Platinum: Platinum spark plugs help to eliminate gap erosion and fire smoothing for a quick start. 

Double platinum: The double platinum spark plugs offer platinum to platinum firing, which is preferred for DIS engines. The plugs provide faster acceleration and offer better fuel efficiency. 

Iridium: Iridium spark plugs are the most technologically advanced plugs available in the market. They deliver better ignitibility, durability, and optimum performance. 

Compatibility Check

Check the manufacturer’s manual of your car whether your preferred plug is compatible with it or not. Also, find the number of plugs required for the engine. 

Pre-gapped Plug Or Not

If you are interested in buying pre-gapped spark plugs, make sure you know the recommended gap instructed in the manufacturer’s manual. Nowadays, most of the plugs available in the market are pre-gapped. You need to adjust the gap for Hyundai Elantra. 

Heat Range

The atmosphere of your place plays a vital role in deciding whether to buy a “hot” or “cold” plug. Hot spark plugs offer a better heat insulator and thus keep the firing tip hotter. On the other hand, cold plugs transfer heat rapidly to keep the firing tip cooler.

Don’t Forget To Check The Nut Size

You should also consider the thread and nuts’ size on the plug that you want to buy. If they perfectly match with your drive, you’re good to go. 

When to Change Spark Plugs Of Hyundai Elantra?

The manufacturer’s manual should instruct you when you need to change the spark plugs of the Hyundai Elantra. Usually, a set of quality spark plugs may last up to 100,000 miles or at least 60,000 miles. However, you may need a new set of plugs earlier or later, depending on your driving pattern and conditions.
