Decent, but be careful of frequent use.
Size: 12 Pairs / 24 pcs, Size: 12 Pairs / 24 pcs
The looks are very nice, functional if left alone once assembled. After that I would leave them alone otherwise you risk the main male portion just coming loose of the housing, sound quality is decent, nothing to write home about, but again, not very durable. If they could fix that 1 thing, these would be very good buy and value, the rest of each plug is hefty and well made.

Fixed my over temp warning issue.
Easy to change and work like new. No more over temp warning at idle.

Works fine. A little pricey but better to buy the best than risk a cheap failure and destroy your engine like i did once.
