Autowxjq Iridium Spark Plug 16pcs Replace Chrysler Dodge Jeep Ram 4.7L 5.7L 6.4L V8

If you own a later-model 4.7L Hemi (2008-2010), you know it requires 16 spark plugs (two per cylinder) to operate efficiently. This kit provides a complete set of 16 high-performance Iridium spark plugs. Iridium has an extremely high melting point, providing superior durability to both heat and electrical wear, making them perfect for modern, high-compression engines. This is a great choice for ensuring the dual-plug system operates at its peak.

– Iridium Design: Offers high durability and is ideal for high-performance engines.
– Pre-gap: Plugs come pre-gapped, allowing for direct installation with minimal fuss.
– Broad Compatibility: Excellent replacement for various OE part numbers (LFR5AIX11, etc.).

Pros:
– Comprehensive 16-plug kit for dual-plug engines.
– Extremely high durability and lifespan due to iridium core.
– Pre-gapped simplifies the installation process.
– Excellent resistance to heat and wear.

Cons:
– Vehicle fitment must be carefully confirmed as this kit covers a wide range of V8s.

Best for: Owners of the later generation 4.7L V8 (2008-2010) or those with other Chrysler/Dodge V8s needing a full set of long-life iridium plugs.

Expert Opinion: The dual-plug 4.7L requires high consistency across all 16 plugs. Iridium ensures that consistency lasts much longer, reducing the complexity and cost associated with frequent 16-plug changes.

8 pc Champion Intake Side Copper Plus Spark Plugs compatible with Dodge Ram 1500 4.7L V8 2008-2010

The 2008-2010 4.7L V8 engine utilizes a two-plug-per-cylinder system, often differentiated by ‘Intake Side’ and ‘Exhaust Side’ plugs. This specific 8-pack of Champion Copper Plus is designed for the intake side plugs, providing an affordable, OE-grade replacement for half of the engine’s ignition system. Champion’s strong track record ensures reliability and compatibility with the sensitive needs of this dual-plug setup.

– You will need to purchase a second set of 8 plugs for the exhaust side for a full change.

Best for: Budget-conscious owners of the 2008-2010 4.7L who are performing their own maintenance and prefer the classic, conductive performance of copper plugs.

Expert Opinion: When dealing with the 16-plug system, using the specified copper plug (which provides the best initial spark) and replacing them at the shorter manufacturer-recommended interval is a highly effective way to maintain peak efficiency.

8 pc Champion Iridium Spark Plugs compatible with Dodge Ram 1500 4.7L V8 2008-2010

For owners of the later 4.7L (2008-2010) who want to minimize the hassle of changing 16 plugs, Champion’s Iridium option is the answer. Iridium provides the maximum service life and consistent performance, resisting wear far better than platinum or copper. While you still need two sets of eight (one for the intake and one for the exhaust), the longevity of these plugs means you’ll be performing the job far less often.

Key features that stand out:
– Iridium Construction: Provides maximum durability and service life, resisting electrical and thermal wear.
– Compatible with 2008-2010: Specifically designed for the later generation 4.7L V8 Ram.
– RELY ON QUALITY: Engineered for long-lasting, powerful performance using durable precious metals.
– Genuine Champion parts: Trusted OE quality and engineering.

Pros:
– Maximum mileage between spark plug changes.
– Excellent choice for maximizing fuel economy over time.
– Highly resistant to fouling and misfiring.

Cons:
– Requires the purchase of two separate 8-packs for a complete engine change.

Best for: 2008-2010 Ram 4.7L owners looking for the longest possible service interval and the most stable performance from their 16-plug system.

Expert Opinion: Changing 16 plugs is a bigger job than 8. If you value your time and want to put the job off as long as possible, the added cost of iridium is absolutely justified here.

Helpful Comparison Short Insights

Choosing the right plug for your 4.7L Ram V8 depends heavily on the model year. For the early 2002-2007 engines, copper is generally the most recommended material for consistency and powerful ignition. The NGK V-Power or the Champion Copper Plus are outstanding choices that offer the best initial spark for these applications.

However, if you’re looking for maximum mileage and longevity in the pre-2008 models, upgrading to the Champion Platinum or the comprehensive Double Iridium Kit (with coils) will significantly extend your service interval, often triple the life of a standard copper plug.

A critical point: if you own a 2008-2010 4.7L, remember that you have a 16-plug system. You must ensure you buy the correct type (intake or exhaust side if buying singles) and purchase 16 plugs in total. Using Champion Iridium plugs in the later models is a smart investment because changing 16 plugs less frequently saves a massive amount of time and effort. If budget is your main concern, the Champion Copper Plus (Intake/Exhaust) can be combined for an affordable 16-plug solution, but be prepared for shorter replacement cycles.

Final Verdict

Making the right choice for your 4.7L V8 comes down to your priorities: longevity, performance, or budget.

If maximum mileage and low maintenance are your goal: Choose the UF270 Ignition Coil & 4503 Double Iridium Spark Plug Kit (for 2002-2007) or the Champion Iridium Spark Plugs (for 2008-2010). The investment in iridium pays off immediately by giving you years of dependable service before the next replacement is needed.

If you prioritize the best possible spark quality and are budget-conscious: Stick with the classic copper plugs. The 8 pc NGK V-Power Spark Plugs offer superior performance and anti-fouling characteristics for the price, providing an excellent, powerful ignition, provided you adhere to regular replacement schedules.

If you need a reliable factory standard plug for the 2002-2007 models: The Champion Platinum Spark Plugs strike the perfect balance between the low cost of copper and the extended life of iridium, making them a fantastic, stress-free option.

Best Spark Plugs For 4.7 Dodge Ram: Frequently Asked Questions

Q1: Why do some 4.7L Dodge Rams require 16 spark plugs?

A: The 4.7L V8 engine was redesigned in 2008 to incorporate a dual-plug ignition system (similar to the Hemi engine) to meet tighter emissions standards and improve fuel efficiency. Models from 2002 to 2007 use the traditional 8-plug system, while the 2008 to 2010 models use 16 plugs (two per cylinder). Always verify your truck’s year before purchasing.

Q2: Is it better to use copper, platinum, or iridium spark plugs in the 4.7L V8?

A: It depends on your driving habits and model year. Copper plugs offer the best electrical conductivity and a powerful initial spark, but wear out fastest (30k miles). Platinum plugs last longer (60k+ miles) and are a good middle-ground. Iridium plugs offer the maximum durability and longevity (up to 100k miles), making them the preferred choice for drivers who want to minimize replacement frequency, especially in the 16-plug system.

Q3: Should spark plugs for the 4.7L Ram be pre-gapped?

A: While many precious metal plugs (iridium/platinum) come pre-gapped and require no adjustment, it is always a best practice to double-check the gap against your owner’s manual or a reliable specification chart before installation. The correct gap is crucial for optimal ignition timing in the Dodge Ram 4.7L V8.

Q4: When should I also replace the ignition coils?

A: If your Ram has over 100,000 miles, or if you are experiencing repeated misfires (especially under heavy load) even after installing new plugs, it’s a strong sign that the ignition coils are failing. Replacing the coils along with the plugs (like in the comprehensive UF270 kit) is a smart way to refresh the entire ignition system and ensure long-term reliability.

Q5: Does the 4.7L engine require special tools for a spark plug change?

A: Yes, you’ll need a torque wrench to ensure plugs are installed to spec, and a specific spark plug socket (usually 5/8 inch, sometimes with a swivel feature) to navigate the engine bay effectively. Proper torque is essential to prevent stripping the threads or having the plug loosen during operation.

Q6: Can using the wrong type of spark plug hurt my 4.7L engine’s performance?

A: Absolutely. Using the wrong heat range, an improper gap, or a plug material not suited for the engine’s design can lead to misfires, reduced fuel economy, and potential engine damage from pre-ignition or fouling. Always stick to the recommended material or a tested long-life replacement like those reviewed here to maintain peak 4.7L Dodge Ram performance.
