5 Best spark plugs for Vortec (Chevy Silverado) & Buyer's Guide (2023)

Our top pick for your Vortec engine is the NGK 5464. The NGK is engineered especially for peak performance from their vehicle. They have high ignitability and very good throttling. They yield unsurpassed in anti-fouling. They really give a car a pep when the vehicle feels weak.

Shawn Jacobsfrom MA, who drives Chevrolet Silverado 2014 says:

My vehicle had been doing pretty badly and it was high time to get a new spark plug for it. I was thinking thoroughly on which one to choose and finally decided to give a try for iridium plugs. After I installed an iridium one (my previous were made of platinum and had about 50k miles of run), believe it or not, my engine was as if it I’d just bought a new car. The performance was perfect and smooth. And there was a dramatic increase in fuel economy. Thus, I can highly recommend iridium spark plugs; the material is much harder and thus lasts much longer than any other!

They typically cost under a 100 dollars and really provide an immediate improvement to the drive performance. They are usable in a variety of models. Drivers of vehicles ranging from the Subaru Bajas to the Toyota Corollas have reported installing this model spark plugs with noticeably improved performance. The versatility and workmanship of these spark plugs are the primary reason we recommend them.

The benefits do not end with the above. It has a long insulator nose that is designed especially to present fouling. There are also other features including corrugated ribs that are engineered to stop flashover. Gas leakage is removed with a three gasket seal. The high temperatures a plug can face is handled by the iridium material with ease. This leads to a long-lasting project that handles extreme temperatures with ease. Anti-corrosion and anti-seizing are also features.

Ordering the NGK is a good decision as the manufacturer packaging is exceptional for protection. The spark plugs in the set are separate. Using additional packaging materials is beneficial to the issues that can come with shipping. You are less likely to receive a damaged spark plug.

These are excellent items. Your Vortec (either 4.3 or 7.0 liters, does not matter) will be noticeably faster and smoother.

Mattew MCrayfrom NY, who drives Chevrolet Silverado SS says:

Installed these last week on my Chevrolet Silverado SS. I had some doubts as for if they really fit my vehicle but I made a right choice and they do a really great job! Just bear in mind that the installation can take longer than you expected, especially it concerns the passenger side spark plug installation. Anyway, everything works perfect, smooth and just as I expected. You can be sure the price is really good for the quality it provides. I am really satisfied with my purchase!

This manufacturer gets consistently high remarks from users online. The Denso 3473 are popular because of the durability. These spark plugs use iridium and have long-lasting properties with a proven reliability history. Iridium is considered a gold standard with spark plugs; this feature attracts many buyers.

The second top-used material is platinum. It is used mostly for mid-level products. The bottom level and cheapest spark plugs are copper ones. Iridium protects the electrode from wear and tear. However, the price is higher than most of the competition. This may be a consideration in your decision in your purchasing decision.

The advantages of the Bosch are that many types of engines that can use them. This means there are many reviews about this company’s plugs. So you can get a really good idea of their quality if you research them. The plugs contain high-quality materials with excellent of German engineering. The Bosch FGR7DQP Platinum is uniquely engineered with four yttrium-ground electrodes. They feature surface air gap firing technology. Their powerful sparking is an achievement of this design.

Have just replaced these spark plugs. I believe that they run with Vortec engine much better than with any others. My car runs now much better and smoother, I can tell you, you will be surprised ot feelyour truck 5 years younger! These spark plugs can be adjusted pretty easily, don’t need to worry about that. But always check the gap before you start installation. I believe they are really good up to 50k but after that they become slow and slack but still your engine will work perfect!. I would really recommend these ones.

The air and fuel mix created by them allow for efficient combustion. Gap wear and oxidation are prevented by the yttrium alloy ground electrodes. Most drivers will be fine using the base settings. The only drawback is that they are made with platinum instead of iridium. Nonetheless, I recommend these as they have a great price point, innovative technology, and German engineering.

Key features:

• Platinum center electrode tip
• Surface air gap technology
• The Platinum+4 delivers a powerful spark for efficient combustion

• Brand: Bosch
