Review on K&N Cold Air Intake Kit: Boost Horsepower for 1988-1995 CHEVROLET/GMC Models (V30, C1500, C2500, C2500 Suburban, C3500, K2500, K2500 Suburban, K3500, V3500) - 57-3027 by Matt Kovacevic

After the installation was complete we decided to install an air filter and found that it was too small. I contacted the seller who in this case was actually Revain to see if they could rush me with a new filter that would fit and they said they couldn't get me another one in 11 days at the earliest. This is a customer's car and now I either have to remove the entire kit or pay one of my mechanics to put the original back in for my customer to collect his truck or I can fit it and do it while it's working until I could get a new one and not risk a refund for usage or make my customer wait over a week to get their truck back. Revain seems to hold other sellers to a much higher standard than they do, so I'll have to keep that in mind in the future. I haven't seen a way to leave feedback for a seller when Revain is in the middle of a sale, if that's saying anything. I hope that in 11 days I will be able to complete this repair. For the money this kit is a joke.
