Help protect your distributor's breaker points and support steady spark delivery with the Standard Ignition Distributor Condenser, part number IH-121. It is a direct-fit replacement for the listed applications, including the 1953-1958 Ford F-100, 1962-1967 Ford Galaxie and 1971-1980 International Scout II. It also covers many more Ford, International and Mercury models.
In a point-type distributor, the condenser works alongside the breaker points. It absorbs the electrical surge when the points open, which is intended to limit arcing across the contacts and help the ignition coil produce its spark.
- Ignition heritage: Standard has served the automotive aftermarket since 1919. As a global manufacturer of original equipment ignition products, it keeps complete quality control from componentry through to the finished product.
- Mylar insulation: High-quality Mylar insulating materials are designed to withstand electrostatic stresses and prevent damage to the internal metal foil windings.
- 100% tested: Every unit is tested so the capacitance value of the finished product meets performance specifications.
- OEM-style connectors: Built for precise installation.
Signs a condenser may need replacing include hard starting, misfiring, weak or no spark, and burned or pitted breaker points. These symptoms can have other causes, so diagnose the ignition system before replacing parts. The condenser is commonly replaced along with the points during a tune-up.
Coverage spans many Ford, International and Mercury models. See the "Vehicles it fits" section for the full list and engine details.

Frequently Asked Questions
What does an ignition condenser do?
In a breaker-point distributor, the condenser absorbs the electrical surge when the points open. This helps limit arcing at the contacts and supports the coil's spark.
Which vehicles does the Standard IH-121 fit?
It fits many vehicles, including the 1953-1958 Ford F-100, 1962-1967 Ford Galaxie and 1971-1980 International Scout II. See the "Vehicles it fits" section for the full list.
Is the IH-121 condenser tested before it ships?
Yes. Standard 100% tests the units so the capacitance value of the finished product meets performance specifications.
What are signs of a failing condenser?
Hard starting, misfiring, weak or no spark, and burned or pitted points may indicate a condenser problem. Other parts can cause these symptoms too, so diagnose the ignition system before replacing.
What part numbers does the IH-121 interchange with?
It interchanges with G111, 3420801, F591, FA66, D9PJ12300A, 1972002, 231596, 360700C1, 86D281A, 58034, 8164851 and FA66SB.
