Buying Ignition Parts for a 2021 Nissan Frontier

On this vehicle, the ignition system delivers spark at the right moment — plugs, coils, wires, distributors and ignition modules.

  • Match the engine first. Some ignition parts fit every engine; others are 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.

Start with the largest groups on this page: Camshaft Position Sensor and Crankshaft Position Sensor .

Frequently Asked Questions

How many ignition parts fit the 2021 Nissan Frontier?

Our catalog currently lists 38 ignition parts for the 2021 Nissan Frontier across 4 subcategories and 15 brands, covering all 3 engine options (2.5L L4, 2.5L L4 DIESEL Turbocharged and 3.8L V6). Each part is matched to the engine(s) it fits.

Do ignition parts differ between 2021 Nissan Frontier engines?

Some do. 1 part fits every engine; the other 37 are engine-specific. Each row (and the filter at the top) shows which. 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 2021 Nissan Frontier?

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 2021 Nissan Frontier?

Notes on this page include pre-set gaps of 0.039", 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 2021 Nissan Frontier 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 2021 Nissan Frontier?

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.
