For the serious gearhead looking to dial in their launch control or overrev protection, this MSD Ignition module kit is exactly what you need. The 87441 specifically covers those odd RPM increments from 4100 all the way up to 4900, giving you five different modules to play with in 200 RPM steps. Think about having that precise control over exactly when your ignition cuts - whether you're setting up for perfect launches at the strip or protecting your engine from accidental overrev situations. Each module is built with MSD's typical attention to detail and reliability, so you know they'll perform consistently when it matters most. The installation is straightforward if you're familiar with performance ignition systems, and being able to quickly swap between different RPM limits means you can adapt to different track conditions or racing scenarios. This isn't for your average daily driver - this is for builds where every detail matters and having that exact control over your RPM limits can mean the difference between a good run and a great one. The modules come in a complete kit so you've got everything you need to start experimenting with different settings. Whether you're running bracket races or just want that extra layer of protection for your high-performance build, having multiple RPM options at your fingertips is incredibly valuable. The quality is exactly what you'd expect from MSD - durable construction that stands up to the heat and vibration of serious racing environments.
