Buying Ignition Parts for a 1972 Triumph TR6

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

  • Confirm you have the 2.5L L6 engine — every part on this page is matched to it.
  • 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: Spark Plug and Spark Plug Wire .

Frequently Asked Questions

How many ignition parts fit the 1972 Triumph TR6?

Our catalog currently lists 60 ignition parts for the 1972 Triumph TR6 across 9 subcategories and 17 brands, covering the 2.5L L6 engine. Each part is matched to the engine(s) it fits.

What are the signs of ignition problems on a 1972 Triumph TR6?

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 1972 Triumph TR6?

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 1972 Triumph TR6 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 1972 Triumph TR6?

Every part on this page is matched to the 2.5L L6 engine. 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.
