Most of my clients are well aware of my passion for trucks and SUVs. I’ll go even further and say that they are very supportive and do their best to give me any feedback on my work. After my review 5 Best spark plugs for GMC Sierra/Yukon, I had many requests to write about GMC Acadia spark plugs.

To be honest I was not in a hurry with a review, but when a few days ago one of my old buddies showed up in my service station in his GMC Acadia with the same question, I decided to do a research and write an article as soon as I could. And here you are. Below is my review of 3 most popular spark plugs for this vehicle.

Best spark plugs for GMC Acadia

Bosch Double Iridium

our-pick
Our rating:
5.0

Compared to traditional copper plugs, these double iridium ones are amazing technological breakthroughs! However, if you still have any difficulties choosing the right stuff, check out my review Iridium vs platinum vs copper spark plugs. It would shed light on all aspects related to plugs’ materials.

These Bosch spark plugs have some very important and exclusive features. Let me outline just some of them:

Double iridium means iridium inlay on both electrodes: firing pin and ground electrode.

This combination ensures four times longer durability and better functioning of the engine.

360˚ continuous laser welding on both electrodes was used to fuse the iridium fine wire firing pin. This 0.6 mm pin ensures better ignitability, and it is responsible for 24% reduction in the voltage.

Bosch double iridium features ribbed insulator helping to avoid flashovers.

Make sure you are buying ORIGINAL Bosch!

Key features:

  • double iridium inlay (iridium firing pin and iridium ground electrode);
  • improved anti-seizing and anti-corrosion;
  • better ignitability and durability;
  • can last 4 times longer durability compared to copper plugs.

Product score:

  • performance (9/10)
  • quality (9/10)
  • price (9/10)

TOTAL SCORE: 9

Pros

ACDelco Iridium

runner-up
Our rating:
4.0

This ACDelco iridium is a great choice for most GMC Acadia trucks. Each plug comes with an original GM part number guarantying exact replacement and high-quality product. Having these plugs in your car you would forget about missing on acceleration, starting issues in cold weather, and rough idling. You will definitely notice smooth work of the engine and increase of truck’s horsepower.

This spark plug features an iridium fine wire center electrode which not only allows for better excitability but also promotes complete burning of carbon buildup on the plug tip.

The plugs are very easy to replace: the whole procedure won’t take a lot of your time. The only thing I would advise you to do is to add a tiny drop of anti-seize stuff on the threads for better protection.

These spark plugs are pre-gapped, however, before installation I would recommend checking gaps according to the manual.

Key features:

  • smooth and boosts engine performance;
  • better ignitability and perfect wear characteristics;
  • longevity;
  • increased fuel economy

Product score:

  • performance (8/10)
  • quality (9/10)
