A 2007 Dodge Ram 1500 with the 5.7L Hemi needs a complete, correctly specified spark-plug set, and this engine uses sixteen plugs rather than the eight found in many V8 applications. This guide compares seven 16-piece choices across conventional nickel-alloy, platinum, and iridium designs. Product fitment ranges here come from current listings, so verify the part number against your VIN and the engine service information before ordering. A longer advertised lifespan or premium electrode material does not make a plug suitable if its heat range, reach, seat, or gap is wrong. The comparison also flags where broad seller fitment claims deserve extra scrutiny.

1. Champion Copper Plus 16-Pack
What We Like
- 16 plugs for the Hemi’s two-plug-per-cylinder layout
- 2003–2008 Ram 1500 5.7L fitment stated
- Genuine Champion product listing
- Conventional replacement option
What We Don’t Like
- Confirm the Champion part number and engine application against your truck before purchase.
For a 2007 Dodge Ram 1500 with the 5.7L Hemi, the important starting point is the exact engine application and the complete quantity. Chrysler’s parts guidance identifies sixteen spark plugs for this Hemi family, with two plugs per cylinder, so a package of eight is not a full-engine set. Champion’s listing identifies a 16-piece Copper Plus set for 2003–2008 Ram 1500 models with the 5.7L V8, so the 2007 Hemi falls within the stated application range. This product’s key distinction is standard nickel-alloy firing ends with a copper core. Treat vehicle coverage and material details as listing claims and confirm them against the truck’s VIN, current engine, and the manufacturer’s application catalog. The 2007 model year can include configuration differences, and the same Ram name alone does not prove that every package is right.
This set is most relevant to buyers who want a conventional replacement set from an established spark-plug brand. Before ordering, match the printed part number, thread reach, heat range, seat type, and specified gap to the service information for your particular engine. Do not choose a plug only because a marketplace title says “Hemi” or lists several years.
A seller catalog can aggregate applications, update its fitment table, or use cross-reference numbers that need confirmation. Check whether the package truly contains sixteen individual plugs and whether any extra installation parts are included; the listing should not be assumed to include wires, coils, or tools unless explicitly stated. Keep the old plugs’ positions and condition available for diagnosis if the engine has a misfire or oil-fouling concern.
My Recommendation
Choose this set if you want buyers who want a conventional replacement set from an established spark-plug brand and its seller-confirmed part number matches your 2007 Ram’s VIN and engine specification. Its main advantage is standard nickel-alloy firing ends with a copper core; its main limitation is that listing fitment must still be verified before purchase.
2. NGK V-Power 16-Pack
What We Like
- 16-piece quantity for a complete change
- 2003–2008 5.7L Ram fitment stated

What We Don’t Like
- The listing does not replace checking the exact plug number and specification.

For a 2007 Dodge Ram 1500 with the 5.7L Hemi, the important starting point is the exact engine application and the complete quantity. Chrysler’s parts guidance identifies sixteen spark plugs for this Hemi family, with two plugs per cylinder, so a package of eight is not a full-engine set. The listing names 2003–2008 Dodge Ram 1500 5.7L V8 fitment and a 16-piece set, making it a direct candidate for the 2007 Hemi if the vehicle details match.

How to Choose Spark Plugs for a 2007 Dodge Ram Hemi
The right choice begins with the exact engine and the plug specification, not the material advertised in a listing. Use your VIN and the service information for your truck to confirm the part number before comparing brands.
Confirm the 16-plug application
The 5.7L Hemi uses sixteen spark plugs, two per cylinder. Check the package quantity and make sure the catalog entry covers a 2007 Ram 1500 with the 5.7L engine. Avoid treating a fitment range for another model year, Ram 2500, or another Hemi vehicle as proof for your truck. A replacement engine or prior modification can also change what is installed, so compare the engine identification and VIN with an authoritative parts catalog or qualified parts counter.
Match the full plug specification
Compare thread diameter and reach, seat design, heat range, resistor type, and gap to the manufacturer’s specification. Champion’s technical guidance says the recommended gap depends on the vehicle; NGK likewise cautions that fine-wire electrodes can be damaged if adjusted carelessly. If a listing says pre-gapped, confirm the setting still matches the 2007 Ram requirement. Do not force a plug with the wrong reach or seat into the cylinder head, and follow the service manual’s torque procedure during installation.
Compare material only after fitment
Standard nickel-alloy, platinum, and iridium plugs differ in construction and cost. A premium metal is not automatically an upgrade for every engine: first match the specified design, then compare brand, package contents, warranty, and seller support. Look closely at broad aftermarket listings that cover many makes and years; verify every cross-reference. If the truck has a misfire, rough idle, or repeat plug fouling, diagnose the cause instead of expecting a different plug material to solve an underlying ignition or engine issue.
Reference sources: Chrysler 2007 tune-up application guide; NGK spark plug gap and installation guidance; Champion spark plug gap guidance.
Before buying, compare the complete OE plug number, thread reach, seat type, resistor requirement, and listed gap. A matching brand or electrode material does not make a plug interchangeable. Use the 2007 Ram service information for the exact engine and follow plug-maker instructions when checking a pre-gapped fine-wire electrode. Stop if the heads or ignition system have been modified.
Frequently Asked Questions
How many spark plugs does a 2007 5.7 Hemi Ram need?
The 5.7L Hemi uses sixteen spark plugs, two per cylinder. Check that a set includes sixteen plugs for a complete replacement.
Can I use iridium plugs instead of standard plugs?
Only if the exact plug’s heat range, dimensions, seat, and gap match the engine specification. Material alone does not confirm compatibility.
Should I adjust a pre-gapped spark plug?
Measure and compare the gap with the vehicle specification. Follow the plug maker’s directions; fine-wire electrodes can be damaged by improper adjustment.
Will a plug set for a Ram 2500 fit my Ram 1500?
Not necessarily. Verify the specific 2007 Ram 1500 5.7L application and part number against your VIN before buying.
Should I replace all 16 plugs at once?
Follow the service schedule and confirm the correct matched set for the exact engine. If one plug fails early, have the cause checked before deciding whether to replace only that plug.
Final Verdict
For a stock 2007 Ram 1500 Hemi, begin with the correct 16-piece application and OE specification. Champion, NGK, and DENSO listings offer clearly named brand options; ENA and BDFHYK are aftermarket alternatives that warrant careful cross-reference checks. Choose only after verifying the exact plug number, gap, heat range, and fitment for your truck.
