Sinister Diesel Recenzje 

They had the part I needed in stock and it was delivered fast.

I ordered the coolant filter kit for a 2006 Cummins. The box arrived without the aluminum filter block. Sinister responded to my email right away and shipped one out same day, so great customer service. Kit was very high quality.

So far so good. Haven’t installed it yet though

Everything

i didn't know the part was on backorder till after I ordered it, that being said they had it to me before the time they said I would after backorder.

Product looks great👍

Received in timely manner and was exactly what I ordered

I bought a blemished exhaust tip. It does what it needs to but an accurate description of the blemished part would have been great not a generic pic that’s not helpful at all

Great price and very helpful product

Everything was as advertised. No issues and it fit perfectly!

product did not fit as perfect as the price reflected i thought i need to tweek the mounting bracket more then i should have to insert into the mounting hole of the removed air filter. still not sure how long the tube will stay on the air intake with the close radius also. time will tell

Quick delivery and great product!

Order was a little wonky at first but they did everything to make it right. Parts work great!

The website is user friendly, product selection is great, prices are competitive and the parts I ordered shipped without delay. I’ll definitely be ordering again from y’all soon.

The ordering and shipping process was super easy and they delivered as promised. Haven't installed the pipe yet, bit thats coming soon amd I'm expecting good things!

Part arrived in the expected time was correct part. Installed easily and appears to be functioning as advertised

Great follow up on an issue I had with installation. It was refreshing when a company really has customer service.

Great price great quality great customer service

Thank you for the honest and speedy reply. I expect that from a reputable business and very much appreciate it. I only wish you had an engine cover to fit my motor. Let me know if you decide to fabricate one for my vehicle. You have fine products. I appreciate the sincere call from Katie and adjusted my rating accordingly.

Original Post
I ordered an engine cover for my 1999 7.3L Powerstroke Ford F250 XLT. Got the part in a reasonable amount of time. It looked amazing and very well built. It didn't come close to fitting my motor. Tried calling customer service CS and was prompted to use the contact us link. I received an RMA in an email with instructions. I mailed it back at my expense ($57) requesting an exchange. I sent another note in the same fashion due to no mention of exchange. Katie
from CS called and left a message that this part did not fit early 1999 model years. Their website part description states, in part .."Fits 1999-2003 Powerstroke." I called Katie back and asked for a "return shipping" refund since this was not my mistake. She said no. Great product, poor return policy for legitimate returns.
