Review on πŸ”₯ BOSCH Ignition Coil 0 221 504 026 - Enhanced SEO-friendly Product Name by William Obong

Revainrating 5 out of 5

Well done as are most Bosch parts

I used these coils on an Abarth Fiat 500. They have been recommended as the number one replacement item when you start to improve engine performance by changing engine management. The original engine setting is 150hp and based on what has been done so far the power is now estimated at around 215hp. Never had a misfire problem, even with over 20psi boost. The planned remapping of the engine control unit will increase the power to 240 hp. The limited slip differential seems to be next.

Pros
  • Coils
Cons
  • Modern
