Denso 671-4049 Coil Over Plug Boot

For 9 dollars you can’t complain about much. Cheaper than the part stores. Just couple minutes to change them. Car was misfiring and it ended up being the coil pack. Figured I’d go ahead and change them before they go bad on a higher mileage vehicle.

Did not need as new coil pack come with them.

Great

Working great in my 2002 Saturn Vue 2.2. You may need some extra di-electric grease. No instructions but easy. Just stick the springs deep enough into the boot so they can't fall out when fitting over the plugs.With these kind of boots it is difficult to know if they fit perfectly over your spark plugs. If it is very hard to close the coil cover then it may not be on right. My car was missing occasionally after my mechanic changed the plugs and when I took off the old boots one of them was bent so that was probably the problem.

Purchased these for my 2006 Chevy Cobalt that has over 200,000mi on it, boots are OEM spec, they work great and my car has its power back like it use to, I've never cared much for Denso products but they did do a good job on manufacturing these boots, I highly recommend it.

Assembled in USAThis kit came with all the necessary parts to replace the boots on my 2006 Chevy Cobalt 2.2 ecotec. It included the boots, springs, and grease. Replacement was a breeze. Quality of the product is excellent.

Buy the Oem misses when wet bad quality

Bought these to install with new spark plugs and a new coil pack for my daughter's 2005 Cavalier. These come with the springs and a packet of dielectric grease. Great price and they fit great, work perfectly.

Good fit and actually came in a 4 pack as apposed to another supplier who is vague about that information.
