Great with a little tweaking
Worked fine on my 99 Blazer (w/4.3L). The only trouble I had was with the end terminals. From the factory they are not crimped down correctly (loose) and you will end up with random misfires to complete failure if you don't crimp them down slightly. I ended up removing the entire set, wire by wire, and hand crimping each end. Fortunately, I had the old spark plugs and coil handy to verify how much was enough crimp on the old parts outside the engine bay. For those that have a blazer, you know how difficult it is to get rid of a 'random misfire' code. Crimping the terminals helped eliminate one point. All in all, lengths and connector type were correct (90's and straight ends) and it did include the correct length coil wire as well. Saved money over a set of OEM as well. Would have been 5 stars but they should know by now how to crimp an end terminal from the factory!

Nice set but if you get a misfire like I did it could be a bad wire like I got.
Nice set of wires but I gave it 4 stars because wire 1 was faulty. Kept getting a cylinder 1 misfire on my OBDII meter. Changed the spark plug twice and even put the old plug back in. Changed my new distributor cap back to the old one. Finally put the old wire back on and that fixed it. Guess I got the bad wire lol.

I figured they all had the 90degree ends like the picture shows
Received today, and I noticed that two of the spark plug ends were not 90degree. I figured they all had the 90degree ends like the picture shows, need them because of headers. Will probably still use them, and other than that they look right and feel solid.

Good Value, Works Well
Good product for the price, one small draw back is the larger diameter of the wires themselves, this made installation a little more time consuming, fitting the wires into hold down brackets took some pressure but did fit ... something I could deal with wouldn't give them a bad rating on account of it.
