HELP SECTION

Speed - the number of cogs on the cassette.

Spline Pattern - the shape of the cogs where they slide on to the freehub body, this must match the spline pattern of your hub to able to fit. In the 1980s Shimano introduced Uniglide cassettes that share the same spline pattern as their now standard Hyperglide, but the smallest sprocket threads on to the hub to secure it rather than using a conventional lockring, these will only fit hubs with a threaded section on the outside of the freehub body.

Range - the number of teeth on the smalles and largest cogs, this gives you an indication of how hard or easy the gearing will be, the lower the number the harder the gears. The tooth count of the cogs inbetween are usually evenly spaced, ie: a 6 speed 14-24 freewheel would likely have cog sizes 14, 16, 18, 20, 22 & 24.

Great plug
Not sure about gas mileage, but these definitely improved the performance of my little 1.8 L Honda Civic, not sure if it’s because the old Plex were just old and weak or just because these are that much better. Acceleration is much better and engine or idle is much smoother

Bosch is a good product in any form
I had used these plugs before in my 03 Honda Element and they performed well for 5 years or more so I considered these for use in my now 07 Honda CRV.

Bosch spark plug are okay... for now.
I'm ususally a Denso Iridium Long-Life or NGK Laser Iridium kind of guy for my Acura or Honda spark plugs. I purchased these on short noticed when I got hit with CEL, grabbed my OBD2 scanner read misfire in all 6 cylinder in my J35a8 (Acura TL Type-S) when I arrived home late that night; I know right, of all places thank goodness. Anyways, I further started to diagnose the car from the least expense before assume the most expensive parts; the spark plugs upon inspection showed they reach it service life. Grabbed my phone in hopes for an overnight prime shipping and encounter these Bosch spark plugs. I installed them the next morning before going to work and all 6 cylinders misfire went away. Sidebar spark plug gap were within factory spec and are somewhat similar to OE. Its been a few week so far still good 👍. For the price it wasn't expensive but I had to order two 4 pack cause the individual spark plug took a few days extra to ship. Gas mileage slightly improve not by a lot, but I'll take it since gas price have gone up. Make sure to properly torque it with either 1/4 or 3/8 torque wrench when I last check they slightly backed out. Since I torque it down to factory recommendation it has stay put since. Will update again in the near future...
