Review on ENA Set of 4 Ignition Coil Pack Compatible with Chevy GMC Pontiac Saturn Malibu HHR Cobalt Equinox Terrain G6 2.4L 2.2L 2.0L - D522C C1552 UF491 Replacement by Victor Correa

With a standard 3/8" socket wrench a 5 year old can break the supplied screws. - I'm picking up on the fact that the negative reviews in capital letters scream o. I was wrong. My guess is that the bolts are low grade stainless steel that reacts and sticks to the engine threads (thread bonding or cold welding). OEM bolts are noticeably heavier in weight and obviously of higher quality. Seller, please specify bolt grade required or remove these bolts entirely from packaging to save future buyers this inconvenience. I got lucky with the extraction (as on the photo shown). The coils have worked well for the last 3000 miles.
