Let customers speak for us
If this works as advertised this will be a great product. Very well built and good hoses. I had an issue with my order and their customer service was great and correct immediately.
Convenient spot for it, though I do wonder about the elevation of it with the added quart of oil vs level with the oil pan. This new location will increase the height of the oil level and may create increased oil pressure.
Top-notch product, quality built, and excellent customer service.
I thought it was a bit spendy, but after getting it, my initial impression is that it’s a very nice kit!! My only problem with the entire kit is the oil pressure sending unit adapter, made from aluminum. Screws into the block, oil lines connect to it as well as the sending unit itself. Too much weight as resting on this part and the first one broke. Sent a new one out and so far so good, but I think it should be SS. Otherwise, great bypass filter kit!!
No noticeable difference, but my CP4 HP Bosch fuel pump is still operational when most everyone else’s has broke and actually under a recall, all with 127,000 miles on it so I’ll give it the btd and give it 5 stars!!
Nice filter!! I can see why it’s as good as it is!! Top notch!!
Love the results, oil analysis looks great even after 400K miles on my 2003 4Runner. Engine is going to outlast the body of my vehicle so I'm thinking of mods and a lift with new brake system and wheels.
Awesome filters, tremendous value, excellent design and quality. I’ve been running these filters for my GM 6L50 transmission. When the fluid was submitted to two different labs for testing after roughly 44,000 miles one of the labs asked why NEW fluid was being submitted for testing! These filters work
This is the best filter I have ever used. The filters were packaged carefully, shipped quickly, and arrived perfectly. I’ve been filtering my oil with these filters for more than 50,000 miles. Now…, the engine oil for my 2017 2.8L diesel is almost too clean to see on the dip stick!
