Liked – nearly exact replica of original, but improved. Very easy install, on my car at least…. Dislike – What appeared to be original cap, was labeled 15lbs. This new cap is labeled as 18lbs. No idea if the larger psi rating is bad, but the car runs consistently at 196 degrees f. So far, functioning very well. 4 Stars. 5 if they explained why it is different from OEM.
