Overview:

ACCEL's patented race proven spark plugs in a Shorty configuration. The overall length has been reduced 3/16 in to 3/8 in (depending on the specific spark plug) to gain critical air gap between the spark plug boot and the exhaust manifold or header tube. This helps eliminate burning the spark plug boot or dimpling the header tube. The shorter spark plug length also can make it easier to install an remove the spark plugs in certain applications where there is not a lot of room to fit a socket or move a wrench around. ACCEL Shorty Spark Plugs are made with a Copper core which is a better conductor than Platinum and Iridium. They deliver a stronger spark especially in high performance applications where high combustion pressures are present. Copper is much better at dissipating heat than other materials which lessens the chance of a misfire. ACCEL Shorty Spark Plugs are gapable allowing you to open the gap exposing a larger flame kernel or close it if needed for high boost applications. All ACCEL Shorty Spark Plugs have machine rolled threads allowing for a more precise thread engagement and torque retention.

Features:

  • Shorty Spark Plugs For Tubular Exhaust Headers
  • Eliminates Dimpling Headers For Added Clearance
  • Improves Spark Plug Access To Fit Socket Or Wrench
  • Shorter Overall Plug Length Vs. OE Style Plug
  • Copper Core Center Electrode
  • Projected Tip
  • Helps Eliminate Burned Spark Plug Boots

Great speaker wire
Size: 14AWG-50FT
I ordered this speaker wire to replace my speakers in my car. I highly appreciated that there are 50' included on this spool, it's perfect for rewiring the stereo speakers in a car (or house). The wire appears to be made well and is the correct gauge. The sound quality is great with my new speakers, and I am highly impressed. I recommend this speaker wire to others, it's exactly what I needed and has met my expectations for high quality speaker wire.

Higher resistance than expected
Size: 14AWG-50FT, Size: 14AWG-50FT
I like Nilight products, I really do, but this one isn’t as good as it could be. After reading other reviews I wanted to take a different test approach and measure the resistance of the whole roll. I thought this might explain the low rating of 5.6A at 12V. I believe my test explains this rating. First, you need to make sure you understand that this is copper clad aluminum. It is clear in the ad title but make sure you are good with that. The test consisted of me removing the entire 50 feet of wire from the spool to reach the other end. I then stripped back the end and tied the two together securely. Only soldering would have produced a more complete contact. I then tested the resistance of the roll with an Agilent U251B multimeter which gave the reading in the pic of .75ohms. That’s not much but compared to what I found on several charts that was high. The average resistance of 14 gauge 41 strand copper wire should be 2.63ohms per 1000 feet or .1315 per 50 feet. The wire tested 5.7 times greater resistance. Obviously aluminum will test with more resistance than pure copper but I was unable to find what those values should be. The insulation is thick and durable so abrasion wear shouldn’t be an issue if routed properly. The wire may still be great for your application but if you are considering pushing this wire to the load limit you may want to upsize to 12 gauge.

Best lights you can get for the best pricing!
Color: 5in Round LED Pod, Color: 5in Round LED Pod
I have had man different off road lights over the years for many different vehicles. Let me tell you about these 5” aux beams. I ordered these lights to go on my 2500 as ditch lights and I am beyond impressed! The lights showed up well packaged. When opening the box, the instructions where right on top and by far one if the easiest sets of instructions I’ve had for wiring diagrams. The lights were packaged and wrapped in foam all the way around to protect them from shipping. The wrapping of the lenses for scratch prevention was perfect. The included wiring harness was packed in a bag and laid out very easily for installation. The harness hooked to the battery and then to the lights with easy quick connects and had more than enough length to put the lights anywhere. Once they were mounted and installed I hooked them up to my aux beams switch panel with ease. Now for the lights! The brightness is beyond bright enough to see miles away! These lights will shine anything you could ever want to see. The spot flood combo work exceptionally well for all situations and darkness. The side shooter stretch them beam out to the sites and can see all the way across. The running lights tie in very easy with your turn signals for extra turn lights or running lights. Heavy duty is an understatement for the quality of these lights. I’m still running them after several months with no water intrusion and still as bright as the day I installed them. The price for what you get, is far beyond better than other top brands! I will be buying more of these for my next off roading set up!

Too big for a tiger, but works well on the fiddy
Color: 4*2.5in Cube LED Pod
Not as bright as the graph says they are, or maybe I'm not in a dark enough area at night. But they definitely are blinding. Were too big for my adv bike unfortunately, but they work good on my truck as ditch lights. Not too bulky looking like the cubes are and no wind noise that I can hear. Definitely lights up the wma trails and the side shooters are very helpful. I will note though that as soon as your hood gets dusty it becomes blinding from the inside side shooters though. so I painted the yellow lens cover on the inside sides and it helps a lot with the hood glare.
