Lowbrow Customs Rtw Spark Plug Holder Review
Never get caught on the side of the road again with fouled spark plugs or with a frustrating motorcycle that won't start with ease. The RTW (Round-The-World) Spark Plug Holder comes complete with a cold-forged, 304 stainless steel multi-tool which allows you to swap out your spark plugs without having any other tools on hand.
The RTW Spark Plug Holder will fit on any motorcycle with a USA-sized motorcycle license plate. The slotted, investment-cast aluminum spark plug holder will mount at the top or bottom of any license plate, or on the backside of your license plate bracket as long as there is room.
Simply unbolt your license plate, bolt the RTW Spark Plug Holder in place and thread in a spare pair of spark plugs. It can also mount to a motorcycle using custom tabs or brackets.
The stainless steel wrench is held in place with a stainless thumb screw featuring a broached allen so it can be tightened or loosened by hand or with an allen wrench (not included). The wrench multi-tool includes a spark plug gapper, an inch and metric ruler, bottle opener, straight screwdriver blade and 1/4" hex driver. Spark plugs not included!
There are two versions of the RTW Spark Plug Holder, one for 14mm spark plugs, which features a 13/16 inch wrench to fit the spark plug hex for spark plug removal and install. The 12mm version features a matching 5/8 inch wrench to fit the spark plug properly.

The round-the-world spark plug holder is a very handy item to keep on your bike at all time. It could potentially help protect you from being stranded on the side of the road with fault spark plugs. The main body of it is investment cast aluminum. You can see the nice lowbrow branding on there, sort of Lowbrow branding. The mounting holes are slotted and what this is intended for, is for mounting onto your license plate bracket. It makes it a really universal product that will fit any motorcycle that's got a license plate bracket. This will work with all United States plates and most of them internationally. It can go on the front of your license plate like a license plate topper. It could go on the backside of your plate bracket if you got an axle or shock mount. It could go horizontal, vertical, pretty much where you want, depending on how visible you want it to be and what style license plate you have on your bike.
There are threaded holes for your spark plugs and the plugs are not included. They will hold your spark plugs at an angle like this, allowing for ample clearance for the mounting hardware. There is also a stainless steel mounting bolt here that's got a broach to Allen and a very deep knurled head. You can get a good grasp on it and remove it with the tool or without.
Go ahead and remove that stainless screw and it lets us separate the wrench. This is a cold forged stainless steel wrench and blazoned with lowbrow customs right here. There are several useful features with this wrench in addition to obviously having the proper size to remove your spark plugs and tightening your new ones, there is a laser engraved metric and standard ruler on the backside as well as having a spark plug gapping tool integrated right into this. A bottle opener, a flat blade screwdriver, and a hack driver. It's the chopper Swiss army knife. It's a very useful tool that can help you change your plugs but also find plenty of other uses on the side of the road or on a camping trip or what-have-you.
There are two varieties of round-the-world spark plug holders depending what make and model year range bike you have. There is the 14 millimeter hole model which is for Harley Davidson Panhead, Shovel Heads model, and Sparters from 54 to 85 as well as Harley Davidson, Big Twin Evo's up to 1999.

How to Install Motorcycle Spark Plug Cap, Terminal & Boot
Todd shows you the proper way to make a set of custom-length spark plug wires for your motorcycle. We often get customers asking how to install the ends on their plug wires, be it one of our vintage-style Cloth Covered Spark Plug Wire Sets or NGK plug caps on silicone wires, or any type of spark plug wires for that matter. In this DIY Tech Tip Video, Todd, Head Motorcycle Tech at Lowbrow Customs, explains how to assemble your spark plug wires, even if you do not have the special crimpers made for the terminal ends.

“Todd from Lowbrow Customs. Today I'm going to show you how to make your own spark plug wires. We have these spark plug wire kits available, they come with three feet of wire also available in various different colors. They also come with two of these Rajah ends, and two of these boots that will go over your coils. And they also come with two of the ends that will plug into the coil.
Okay, first thing we want to do is make sure you square the wire you want a nice clean cut on the end, and then you're going to strip off probably about a quarter of an inch, being careful not to cut into the core of the wire with your strippers. Then you're going to take your Rajah end. You're just going to unthread, it has threads on it. Then take this end here, and slide it over the wire. Now, you've got the wire protruding up through the middle of it.
And you're just going to thread this other end of it on to there with the point facing in, which will make the electrical connection. Nice and tight, simple. Okay, now obviously once you've got that done you should plug that onto your plug wire, and figure out how long you need it to go to the coil. And at the other end, the first thing you want to do is slide the rubber boot over the wire because it won't be able to go on after the connector's on there.
Little bit of lubrication doesn't hurt here. Okay, do I like to do these ends? What I do is I strip about 3/4 of an inch once again being careful not to cut through the copper core. give it a little twist, and fold the wire over the outside of the cloth covering. Let's give us a little bit more room to work here. Okay, then you're going to take one of these ends that will plug into your coil.
There is a fancy tool made for these to do this crimp, and make it beautiful, but not everybody has that tool in their garage. What I like to do is I'll take a pair of needle nose, and I'll just take the end that's going to get crimped, and kind of fold it over a little bit, till it looks like that. Okay, what you want to do is you want to slide the wire with the part that you stripped, and put it to the bottom so that the crimp is on the opposite side of the wire.
You also want to leave yourself a little room there so that it ends up looking like that before you crimp it so that it can engage into the coil properly. Just taking whatever pliers you have around the garage, and kind of squeeze it together, fold it down a little bit. I always want to make sure anytime you crimp something onto a wire that it's secure, it's not going to pull back off, and that's about what it should look like when you're done.
Also when you go to plug this in the coil if it's not a tight fit you can always bend these out a little bit, and then the first time you plug it in it will fit tighter. If it feels loose in the coil just bend it a little bit. We also have these NGK ends available for spark plug wires. These form a nice tight watertight good connection if you have a magneto type ignition probably not a bad idea to have these resistor caps on there. They're simple to install.
These have a point inside the end what you're going to do is you're just going to square your wire up, first you're going to put the boot over this. Okay, you're going to slide the lower boot over the wire, then you're just going to thread this in like you're screwing it. Try to get the wire, the point of the screw inside here you go right directly down the center so it's making good contact with the copper core of the wire, and you're just going to thread that on like so till you feel a tight resistance, that tells you that's threaded on as far as it will go.
Then you can slide the boot over the end of the cap. There are three little notches on the end of here, and that keeps it from pulling off. Once again a little bit of loop probably wouldn't hurt there. There you go that's what it looks like with that on there, and that also comes with a boot that you can put here. Slides over the end of that like so, so when you plug that onto your spark plug forms a nice seal.
Good option. We also have the spark plug wire available by the foot. If you want to just order the wire, and a couple these ends, you can do it that way also.”
