Buying Ignition Parts for a 1966 Checker Aerobus

- 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

Our catalog currently lists 49 ignition parts for the 1966 Checker Aerobus across 8 subcategories and 15 brands, covering all 4 engine options (3.8L 230cid L6, 4.6L 283cid V8, 5.2L 318cid V8 and 5.3L 327cid V8). Each part is matched to the engine(s) it fits.
Do ignition parts differ between 1966 Checker Aerobus 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 1966 Checker Aerobus?
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 1966 Checker Aerobus?
Notes on this page include a 0.035" pre-set gap. 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 1966 Checker Aerobus 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 1966 Checker Aerobus?
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.
