Hard starts, rough idle, misfires under load — ignition components wear gradually, then fail all at once. This collection covers over 50 BOXI ignition and tune-up replacement listings, including coils and related components, each cross-referenced to OEM and interchange numbers.

We manufacture the BOXI line ourselves and ship free from Montclair, California — same-day dispatch before 1:00 PM PT, 3–5 business day transit, 2-year warranty.
