Ordered a set of intake ducts for my track plastics since the stock ones were too big to use. I was worried that these wouldn't work with my Harris Racing Plastics, but I gave them a shot anyways.
Thought they took a little bit to get here, most likely due to being "made on order". Either way, they stayed in contact at each step.
Got them in and test fit them today. Fit like a champ! Pretty impressed and happy.
