Review on Spectra Premium C-528 Coil-on-Plug Ignition System by Bishnu Bush

After studying the manufacturer; I ordered 6 for a 2002 Toyota Camry V6 for 190,000. They fit snugly and after 2 months of use they seem fine. The cost is about half that of the dealer. UPDATE: One was buggy new (worked fine, installed code). Manufacturer replaced but I paid S&H to return the defective one. Yesterday (within 4 months of installation) the car had a serious misfire and several codes were set. The need to start the car as soon as possible and the reluctance to pay again for the same part; I bought 4 more from the junkyard and replaced the bad blocks. It's a shame when the original devices from the junkyard work better than these! I do NOT recommend!
