Not really as all the re popped ones I've seen and bought are about the same. Here's a brand new GM one on the left and one from Napa on the right. As you can see the GM one has alot more rubber impregnated into it but is a lot cruder looking than the Napa one. The GM came from Finland while the Napa one is from India. I've used the Napa ones in three or four cars around here and haven't had any problems at all and they are CHEAP.
