Chevy/GMC 6.6 liter Diesel Glow Plugs

We love the full line of parts they carry for our fleet of vehicles

I have been ordering filters here for as long as I've owned my trucks and they are always very fast and economical. On the phone they are very personable. I will continue to use them for any parts I can get from them!

this place has the best knowledgeable sales team ever. Love doing business with them.

This place is extremely impressive as far as pricing to every breathtaking detail customer service provides us. We have a huge fleet of vehicles that we purchase parts for and they never rush me, and make sure they have covered the parts for every vehicle. This place is IMPRESSIVE!

I would not but from any other place. From the very helpful sales associates down to the care they take shipping your package, you can tell this company and it's employees are really passionate about what they do!

I just love the wealth of knowledge at this place they know things about my truck that even I don't!!!!!!!!!

Amazing prices, and fast shipping. My local Ford dealer is horrible and I like that I can buy factory filters from dieselfiltersonline much cheaper and not support my local dealer.

Don't know quite where to start. I have been purchasing a equivalent brand filter and paying more than the oem ones this place sells. Don't know how they do it but I sure do appreciate this place. They are saving me money and I am happy having the oem filters back on my truck

I found this place while searching for a part for my truck and thought I was going to order it from Amazon UNTIL I CALLED THIS PLACE. I didn't think you could talk to a live person anymore, but I got a real live person and she was more than willing to assist me with my needs and she told me about the rewards program they have with 1% back on my purchases. Turns out they are cheaper than Amazon. My new go to place.

This is the only place I can find great parts, pricing and customer service for my truck. I will buy from them forever!

This place should be called the world's BEST filter company. Rock on dieselfiltersonline for providing me with superior pricing and customer service!

I'm a new customer and I think I'm gonna like it ! The guy who took my order for my truck didn't talk down to me just because I was a girl... I do work on my own truck with some help from a friend of mine so I know a lot about the underneath of a car/truck because my dad had race cars when I was growing up which lead to my working on my own cars when I got older however like everything else engines have changed drasticly since the early 80's and while I still understand the principals I am lost at all the new gagitts with vacuum this at sensor that... so while I was ordering my parts I was very glad the the customer service guy could understand what I was asking for even though I wasn't calling the parts by their proper name... great company and great customer service. Oh and he was very knowledgeable as well ! He knew that after about 100,000 miles the f350's water cap sensor something that has to do with fuel filter changing cracks on the top and in Ohio where there's the extreme of got and cold this seems to accelerate this process... Thank u Deiselfilters !

I cannot believe what a huge selection of oem parts this place carries. And the PRICES are at least 1/2 of other places. I will definitely be doing all of my shopping at this place.

Love how this places does their homework and finds who makes the items for the major compaines and saves you every dollar possible. I always revceive great customer service to boot!

The knowledge of this place is spot on. I called to order a fuel filter kit and oil filter and the lady on the phone asked me how many miles did I have on my truck. I told her almost 60k she asked me if the dealer told me that I had a ccv crankcase breather element. I asked what is that and she explained it to me and even told me how and how easy it was to change it. THEY GOT MY BUSINESS! And hats off to the sales staff

This place always has the right price (better than anyone for the parts) I am always looking for!

as the bottom of my invoice says PROVIDING ME WITH SUPERIOR CUSTOMER SERVICE! Thank You Dieselfiltersonline!

We have been ordering our parts for our fleet of vehicles here for the last several years and this company just keeps getting better expanding products we need to if I don't see it I can call them and they tell me how long till they can get it.
