2010 Chevrolet Cobalt L4 2.0L Turbo 4 Piece Ignition Coil Boot Set TRQ ICA30420

I will install in a few more days. It looks alright but could have used instructions/ pictures as to be sure how it went together. Was a great price! Note: Something I learned was that went a plug gets carbon tracks down the top white part to the metal base (from the top plug cap- were the spark starts, down the white insulator to the metal base were the bolt head part is) it can transfer on to the PLUG BOOT (inside the boot!) and if not replaced it can transfer from the old boot to the new plug or just jump and cause a miss-fire! I find that plugs will go 100,000 miles but are in poor shape so changing at 75,000 or less is better... AND change the PLUG BOOTS too! If you can't afford it then every other time may work. 1A AUTO has a deal on the Plugs with the Plug BOOTS as a set... Also a deal on the coils with boots and with plugs too. check that out $$$$
