    Carb plugs

    Can someone point in the right direction or educate me on the purpose of the little rubber plugs on the jet block. I can find very little info on their actual purpose. Can the plugs be disposed and the port sealed? do they affect performance? Etc...

    Brisk plugs

    Anyone use these? I guess cause they look cool and different that they might be better than standard plugs. https://youtu.be/9PJweiCRFoU Sent from my iPhone using Tapatalk

    Plugs from my 93 Max

    Well I had some time today after a lil ride :biglaugh: to see what the plugs looked like from the previous owner. Here they are. I know this isn't a throttle chop...but it looks a lil lean to me. As far as I know, it's completely stock. Exhaust everything. Thoughts?

    Water jacket plugs

    Just an fyi, when you are flushing or replacing your coolant and want to remove the four rubber plugs on the cylinder sleeves, if you dont have a spare spark plug laying around you can always use a garden variety 4mm x 0.70p bolt or screw. Peace

    NGK Platinum Spark Plugs?

    I had a plug die on me, so decided to swap them all out. I was intending to replace them will the same NGK DPR8-ea9, but the store was out of stock. Instead the guy recommended an alternative NGK plug which he said was a platinum tip. I can't remember, but I think it was something like DP8-efg...

    Changed the spark plugs in my f150

    I am sure glad plugs these days last a long time. 130,000 miles on this set. The gap was .074 on the old plugs .054 is spec. I have an 06 with the 4.6 liter, while it's not the hardest job i have ever done, it is very involved. Makes working on the Vmax seem easy. I finally bought a neat...

    Plugs and Heat

    Guys. have you seen were 1 plug looks to be extremely hot and melting the stock rubber boot and the others are fine? #2 seems to be melting the boot. #1,3 and 4 are fine. Come next spring, I have to get a temp reading on #2.

    Weird caps on plugs

    So as I'm investigating and fixing things on the '86 I found a little cap screwed onto one of the spark plugs. I'm out and haven't checked others yet, but let's assume they're on all the plugs. What the heck are they? It made it basically impossible to push the plug wires onto the plugs. I'll...

    Iridium plugs

    Anyone using the NGK iridium plugs? I have seen the correct part number as DPR8EIX-9 and the plug looks like the one below. However when I pulled the installed plugs the connector is the threaded rod style and these connectors won't fit. What is alternate part number?

    Another Plug Thread.. Remove OEM? Replace?

    When I bought Karma last year she didn't come with the kit under the seat. What is the best and easiest way to remove my plugs? I've heard OEM Plugs are the way to go. I can't use the Search engine on the VMF with this so called top of the line cell phone.:bang head: KarmaKatt
