Response from Diesel Ops· Jan 5, 2017
Hello Lisandro, I am sorry to hear you did not get the part you ordered I do want to make sure you have had this handled and would like the chance to get this handled for you ASAP. This is not something that I am ok with seeing and hearing from customers. Please call me and let me get the chance to get you settled and get you happy with working with Diesel Ops again. Looking forward to hearing from you so we can get you taken care of Chris (Sales Manager) 888-992-7299 ext 702
Ordered my intake and two days later it was on my door step. Fast shipping, great customer service and it's obvious you guys love your logo because you didn't skimp out on the stickers at all. But honesty no need to improve on anything in my book. My trucks breathing better sounds better and has noticeable better response A+ I'm impressed
