I called the customer service line just before Air Venture at Oshkosh to find out if they would have the parts I needed at their booth. The service rep on the phone was very helpful and was able to check the inventory that was taken to Oshkosh.I was told that the parts would not be available but could be shipped from the warehouse without delay. I ordered a full set of intake seals for a Continental 085 on the spot and they arrived in a few days. I am very happy with the service provided, and will be ordering more parts soon! Thank you Larry

Have to tell you that you have the best in Brittany Cornish. She is always the most help in getting our ordered placed as soon as we send it in and always on time delivery. She is very responsive with any and all issues if any which we never have any dealing with her. She always goes above and beyond to follow up even after we received our order. We only wish all of our Vendors that we deal with on a daily basis were as wonderful as she is. Her personality is bar none.
