Not sure where you are pricing your stuff

Chrysler ICU - $13.88
GM ICU - $9.54
Ford TFI Coil - $8.66

Cheapest regular priced options at RA. Pretty sure I wouldn't use those options in any case, but the point it it's not really cheaper.

You price the high end and the GM/Ford combo is about twice the Mopar ICU cost.

They say there are no such thing as a stupid question.
They say there is always the exception that proves the rule.
Don't be the exception.
