Upgrade ignition coils

Hi folks! Getting to be that time for new plugs on my 2011 Ram 1500. My truck has 99,500 miles as of today and since the plugs are being changed soon, I want to put a new set of coils on as well- just in case the oem"s are getting tired. I'm the type of person that if I'm going to fix/change something.....put a better replacement in its place. So...my question is.....fresh set of OEM ignition coils or go for RIPP or MSD's? Getting mixed reviews on MSDs so I'm leaning towards a set of RIPP coils. Truck is a daily driver.....cold air intake and exhaust only but still- if needed....I want it to not hesitate to get up and go!(which it does now). Any input would be greatly appreciated! Thanks everyone

They don't really get tired, just run to fail. Replace with OEM. The new Demon 170 can make over 1000 hp........on stock coils.

After 06 the OEM coils are hard to beat, MSD, are fine for alum valve cover 5.7s, not worth the extra coin for 95% of the daily crowd. I’ve seen the OEM dual coils hit 300k miles and be within 99% of spec output voltage.

our 2015 drag pack clone, made roughly 1250hp with oem coils , made roughly 1250 with ripp coils., made 1190 with accel no roughly about that one , msd, had a better average power, but not enough to warrant the cost.
