Colorado ignition coils first gen.
I purchased the set of 5 for a great price. A little worried about the cheap price but we will see after time if they are good for the long run. Very easy to install. 4 hose clamp screws. 2 bolts and 1 vacuum hose to get to them. 1 electric plug and 1 screw to remove the coil. They look very nice and not cheap.seem to be working fine. Truck runs great. 2006 Chevy Colorado crew cab.

So far so Great
I have to admit I was a little skeptical at first. ...usually less expensive means cheap....not the case so far with these coil packs. Good buy.

Solved multiple misfires 04 Colorado
Product quality is same as factory at a fraction of price. I have been dealing with multiple random misfires and nobody could figure out why. My mechanic said I had clogged injectors and did an $100 induction service to no avail. He also said he tested the coils and they were fine. The misfires were more often in cold weather. So I went out on a limb and ordered this set. No more misfires!!!
