Had an orileys one and it lasted a year, sometimes fomoco is the only way to go. First one lasted300k miles

Some things you can buy after market other things you can't. This block heater is way better than any aftermarket turd... make the choice for yourself

After the postal service sent it all over the Us,US , itfits and works perfectly on my 99 7.3, i do business with RiffRaff because they are not ashamed of the Gospel, which bring salvation to men

in have been having trouble with these burning out in a couple months,,,this one does not seem to get as hot as the last couple,,,we will see if it lasts longer

Oem heater installed in about 5 mins. Love it. Fast shipping as usual

Mine was working, but close to failing at 289k and 17 years on my 03, drooping down when removed. Reworked my oil cooler and did this maintenance item while I was at it. Recommend replacing if old like mine and used in cold winters.

i have never seen such fast shipping and the best customer service anywhere,,,i will shop no where else for parts .....

Solid and well made coil, shipped Quickly and good price

As always, when I need the right part, RiffRaff delivers.
Authentic OEM block heater. The original lasted since 2001.
