AndreanaT: Shipping was crazy fast! Took about 10-15 minutes to remove old bolts and install these. Nice little mod for the engine bay. Bought the 14pc set and used them all in my 14 Sonata. Will be buying more from K5 for sure!
John G.: Installation was easy with no issues so far. Throttle response feels much better and the sound, oh the sound is FANTASTIC! Super fast shipping and Dave has tried to answer any questions I had.
