Our catalog currently lists 25 ignition parts for the 1964 Triumph TR4 across 6 subcategories and 12 brands, covering both the 2.0L L4 and the 2.1L L4. Each part is matched to the engine(s) it fits.
Do ignition parts differ between 1964 Triumph TR4 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 1964 Triumph TR4?
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 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 1964 Triumph TR4 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 1964 Triumph TR4?
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.
