NGK G-Power Platinum Spark Plug TR5GP (8 Pack) for CHEVROLET SILVERADO 1500 LT 1999-2013 5.3L/325

While this particular listing is aimed primarily at older Silverado models (Gen III/IV up to 2013), the NGK G-Power Platinum plugs represent a fantastic cost-effective option if you are seeking reliable, traditional Platinum performance. Platinum offers better corrosion resistance and heat dissipation than standard copper plugs. They feature a fine wire platinum tipped center electrode that significantly aids in easier starts and can provide a slight boost in fuel economy compared to old, worn-out plugs. Note: If purchasing for a 2017 model, always double-check the exact part number required for your engine code, as the primary fitment shown is for older engines.

Key features that stand out:
– Fine Wire Platinum Tip: Reduces required ignition voltage for better starting.
– Trivalent Metal Plating: Provides excellent anti-corrosion and anti-seizing protection.
– Copper Core: Aids efficiently in heat removal from the tip.
– Corrugated ribs prevent “flashover” (spark traveling externally).

Pros:
– Excellent budget-friendly alternative.
– Superior anti-corrosion and anti-seizing properties.
– Reliable ignition stability.
– Improved heat transfer over standard plugs.

Cons:
– Platinum lifespan is typically shorter than Iridium for modern high-performance engines.

Best for:
Budget-conscious buyers looking for reliable platinum performance (but verify fitment for 2017 5.3L L83 engines carefully).

Expert Opinion: Platinum plugs are a reliable baseline, known for their quick starting ability thanks to the reduced voltage requirement. For a lightly used 2017 Silverado that mainly sees city driving, a good quality Platinum plug can offer great value without sacrificing too much longevity.

Round Ignition Coil Packs Spark Plugs fit for V8 5.3 6.2 2014 2015 2016 2017 2018 2019 2020 Chevy Silverado 1500 Suburban Tahoe Corvette Camaro, GMC Sierra Yukon XL, Cadillac Escalade CTS ESV, UF742

This is a comprehensive replacement kit, which is often necessary when diagnosing serious engine misfires or rough idling in a 2017 Silverado 1500. It includes 8 ignition coils (UF742) and 8 pre-gapped spark plugs. The coils are responsible for boosting the battery voltage needed to fire the plugs; if they are failing due to heat or age, simply replacing the plugs won’t solve your issues. This kit simplifies maintenance by providing both crucial components designed to work together perfectly.

Key features that stand out:
– Complete Kit: Includes 8 ignition coils and 8 spark plugs.
– Coil Interchange Number UF742: Direct replacement for common OE part numbers.
– Addresses System Failure: Ideal solution when experiencing misfires likely caused by aging coils.
– Guaranteed Compatibility: Fitment verified for the 2014-2019 V8 5.3L and 6.2L engines.

Pros:
– Solves complex misfire issues stemming from coil failure.
– Excellent value for replacing both major ignition components at once.
– Simplifies the maintenance process.
– Ensures reliable, coordinated spark delivery.

Cons:
– May be overkill if only the spark plugs are genuinely worn out.

Best for:
Silverado owners battling persistent misfires or experiencing overall poor ignition system health.

Expert Opinion: When a 2017 Silverado hits high mileage (over 120,000 miles), ignition coils can start to degrade, especially in hot environments. If you suspect coil failure, don’t waste time replacing just the plugs. This type of comprehensive kit provides peace of mind and restores the entire system to peak operational health.

Comparison Insights on Best Spark Plugs For 2017 Chevy Silverado 1500

Choosing the right plug depends heavily on your priorities: performance, longevity, or budget.

For maximum engine efficiency and a slight bump in acceleration, the NGK Iridium IX plugs (Products 1 and 3) are the clear winners, offering the sharpest, most powerful spark. Iridium is significantly harder than Platinum, meaning the fine center electrode resists erosion better than any other material.

If your primary goal is to install the plugs and forget about them for a long time, the A-Premium Iridium Platinum option is highly competitive, boasting replacement intervals of up to 100,000 miles. This dual-metal design provides great longevity at a competitive price point.

If you’re hunting for the best value in a precious metal plug, the NGK G-Power Platinum is a good entry point, but remember to verify that the TR5GP heat range is appropriate for your specific 2017 engine code (especially the L83 5.3L).

Finally, if your 2017 Silverado is experiencing rough idle or stuttering that doesn’t clear up after routine maintenance, the Coil Packs and Spark Plugs Kit is the most practical solution, guaranteeing you address both wear items in the ignition system simultaneously.

Final Verdict: Our Top Picks for the 2017 Silverado 1500

Making the final call on the best option can be tough, but we’ve broken down our recommendations based on three common scenarios for 2017 Chevy Silverado 1500 owners:

The Best All-Around Performer: We recommend the NGK Iridium IX Spark Plugs. They provide exceptional ignitability, reliably reduce misfires, and offer the strongest, most consistent spark—essential characteristics for the high-compression, direct-injection EcoTec3 V8 engines.

The Best Choice for High-Mileage Drivers (Longevity): Go with the A-Premium Iridium Platinum Spark Plugs. Their construction is explicitly designed for extended service life, meaning fewer changes and more time driving without worrying about maintenance.

FAQ: Best Spark Plugs For 2017 Chevy Silverado 1500

What are the main signs that my 2017 Silverado 1500 needs new spark plugs?

Common signs include rough idling, difficulty starting (especially in cold weather), a noticeable decrease in fuel economy, and poor acceleration or hesitation when stepping on the gas. If you have the check engine light illuminated, a diagnostic scan will often show specific engine misfire codes related to worn spark plugs or ignition coils.

What is the recommended service interval for spark plugs in a 2017 Chevy Silverado 1500?

For the factory-installed iridium plugs on the 5.3L and 6.2L engines, GM typically recommends replacement between 75,000 and 100,000 miles. However, if you use your truck heavily for towing or frequent short trips, checking them closer to the 75,000-mile mark is advisable to maintain peak towing performance and engine health.

Should I choose Iridium or Platinum spark plugs for my 5.3L V8 engine?

Iridium is generally superior for modern engines like the L83/L86 in the 2017 Silverado. Iridium is harder and allows for a finer electrode tip, which creates a more efficient, powerful spark. While platinum plugs (like the G-Power) are reliable and cheaper, Iridium plugs offer better longevity and improved ignition performance, making them the better choice for the high heat produced by direct-injection engines.

What is the correct plug gap for the 2017 Silverado 1500 5.3L or 6.2L V8?

The factory recommended plug gap for these engines is typically 0.040 inches (or 1.02 mm). While many aftermarket plugs come pre-gapped, always double-check this specification using a wire gauge during the DIY installation process, as a slight bump during shipping can throw the gap off.

Is it necessary to replace the ignition coils when changing the spark plugs?

It is not always necessary, but it is highly recommended if your 2017 Silverado is approaching or exceeding 120,000 miles, or if you are already experiencing misfires. Coils have a lifespan, and replacing them alongside the plugs (as offered in the comprehensive kits) ensures the entire ignition system is refreshed, protecting your investment in the new spark plugs.

Does the choice of spark plug affect fuel economy in the Silverado?

Yes, absolutely. Worn or fouled spark plugs lead to incomplete combustion, meaning your engine has to inject more fuel to compensate for the power loss, negatively impacting your fuel economy. Installing a new, high-efficiency plug (especially a fine-wire Iridium option) restores combustion efficiency and can noticeably improve mileage compared to running on old plugs.
