    Installation took less than 30 minutes for all 6 plugs. It'll take longer if you have the coil instead of a distributor. Gaps were already pretty close to the specified plug gap so I just threw them in there.

    Only thing I didn't like was the washers on the spark plug were not put on from the factory. I'm guessing this is because some Cherokees have aluminum heads while others do not.

    Car seems to be running smoother, the old Boush plugs were old though so time will tell. I would definetely buy this plug again.

    I seldom review items, however, I recently installed NGK-V into a Dodge Ram and these Autolite plugs into a Jeep Wrangler. The NGK plugs were all gapped at .35 with a protective sleeve at electrode. The Autolite plugs had NO protective sleeve and all had to be gapped. I recently bought the Jeep and replaced a set of Bosch Platinum +4. The old Bosch Platinum + 4 started the Jeep much better and faster than the Autolite plugs. I have not even driven and can advise that the Autolite Plugs are not as easy to install as the NGK's because they all needed to be gapped and they certainly do not start the Jeep as well as the old Bosch Platinum +4. The Jeep needs to crank over several times before it will fire. It does idle smooth once started but why do the extra work for less at least starting performance? I would NOT recommend and will not buy Autolite Plugs again.

      The plugs were everything I expected them to be. For my application I didn't need the expensive platinum plug, so these worked out really well.

                  a plug is a plug. my mach. told me a long time ago that a plug makes a spark that is all you need. So why pay over 2 bucks for a plug. when a plug is a plug. if you want to blow your $ and pay 10 bucks for a plug when a 2$ plug will do go for it.
                  I will still win

                          I'm glad to assist, Mike! These spark plugs should last approximately 30,000 miles under normal use. I suggest following your vehicle manufacturers standard service intervals for the spark plugs.
