Buying Ignition Parts for a 2012 Chrysler 300
On this vehicle, the ignition system delivers spark at the right moment — plugs, coils, wires, distributors and ignition modules.
- Match the engine first. Every ignition part here is engine-specific; each row shows which engine(s) it fits.
- Read the notes on each row for position, trim and spec qualifiers before you order.
- Where labor overlaps, replace plugs and wires (or coil boots) as a set — one weak cylinder makes the whole set feel bad.
- Cross-reference the manufacturer part number against your old part or a service-manual listing.

Frequently Asked Questions
How many ignition parts fit the 2012 Chrysler 300?
Our catalog currently lists 76 ignition parts for the 2012 Chrysler 300 across 10 subcategories and 27 brands, covering all 3 engine options (3.6L V6, 5.7L V8 and 6.4L V8). Each part is matched to the engine(s) it fits.
Do ignition parts differ between 2012 Chrysler 300 engines?
Yes. Every ignition part on this page is engine-specific. Each row shows which engine(s) it fits — use the filter at the top to hide the rest. If you're unsure which engine you have, check the emissions label under the hood or the 8th character of your VIN.
What are the signs of ignition problems on a 2012 Chrysler 300?
Common symptoms include misfires under load, rough idle, flashing check-engine light, or poor starting in damp weather. If you notice any of these, identify the affected subcategory above and cross-reference the part numbers listed.
What spark-plug gap is listed for the 2012 Chrysler 300?
Notes on this page include pre-set gaps of 0.032", 0.035", 0.040", 0.041", 0.043" and 0.044". Still verify against spec — even “pre-gapped” plugs should be checked before they go in.
What should I replace at the same time?
Where labor overlaps, replace plugs and wires (or coil boots) as a set — one weak cylinder makes the whole set feel bad.
What do the market flags (US, CA, MX) on each part mean?
They show the market for which the manufacturer published application data for that part — where the vehicle was first sold, not where the part was made. If your 2012 Chrysler 300 was originally sold in the US, the safest choice is a part marked for the US market.
How do I make sure a part fits my 2012 Chrysler 300?
First match the engine — each row shows which engine(s) the part fits. Then gap matters even on “pre-gapped” plugs — verify against spec, and replace coil boots when they come off a high-mileage engine. The notes column carries position and trim qualifiers where they apply.
