This upgraded battery cable kit replaces old worn out battery cables for more power and better performance from your vehicle.

What's the Big 3, and why do you sell a "Big 7"?

The "Big 3" (or sometimes called "Big 4") upgrade means improving the current capacity of three cables: 1) alternator output to battery positive, 2) battery negative to frame/body, and 3) engine ground to frame/body. We don't stop there though. Our "Big 7" kits also include the leads to the starter and the fuse relay box, as well as adding an external fuse to avoid routing the increase in current capacity through the smaller fuse box wiring.

What makes these cables so special?

We're nerds for specs and finer details around here. None of that CCA (copper-clad aluminum) that's used in inferior products, or stereo installations. We only use fine-strand, SAE (Society of Automotive Engineers) approved, pure copper cable. Then using a powerful electromechanical crimping machine, we crimp each solid-copper end, and finally finish the construction by adding a environmental seal made of marine grade heatshrink meeting MIL-I-23053/4. Also included are military style corrosion resistant battery connections and a MEGA fuse and holder. To make the entire install simpler, every end will be labeled for ease of installation. Our Toyota 4Runner Battery Cable Replacement Kits are built to this exact standard, giving 4Runner owners a direct-fit, premium upgrade that outperforms factory wiring in every way

Do I need a bigger alternator to run these cables?

No. Every vehicle can benefit from our "better than factory" cables. The years, along with environmental damage from rain/salt water/corrosion, can greatly impact your electrical system. Our customers have consistently reported that their vehicle starts faster, charges the battery better, and many times cured electrical gremlins that were brought on by compromised wiring.

I've changed my mind! I want to run a bigger alternator!

Perfect! You're probably running a power inverter, a stereo, a winch, an under hood welder, or flux capacitor. These all require more amperage than the stock alternator is capable of providing. Maybe you're not running any of these yet, but considering it, these cables will get you ready!

2GA or 1/0 GA? Which to choose?

As far as 2GA vs 1/0 GA, it's really going to depend on what mods you're going to do to. If you're staying stock, then 2GA is plenty, but if you're looking at modifying it down the road (winches/lights/etc) and want to future proof, then you'd want 1/0 GA.

Better than Honda Cabin Filter for Allergies -
Size: 8.3" x 9.3" x 1.3"
Installation took all of 3 minutes. Noticeable improvement in air quality (less allergy response) since installation. Others mentioned a reduction in air flow but have not noticed a change. ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, Update (9/2020) Noticeable reduction in air flow. I have needed to increase the fan speed to make the cabin comfortable. I may be switching brands soon. I will pull the filter at 6 weeks and see if it is getting plugged (yikes). //////////// Update (10/2020) I pulled the Bosch filter expecting it to be plugged due to the lack of air flow. I was surprised to see it was clean. There were are few small pieces of stuff in the folds of the filter but only about 10 of them. I held the filter up to the light and then tapped it on white paper to see what would fall out. There was nothing present to explain the extreme loss of air flow. I have used Bosch cabin filters in my other vehicles (not HEPA) with great success. I was hoping to help the allergies of my family but having to run the fan on high to receive any airflow was more annoying than helpful. The noise was irritating and the air flow was still less than the Honda filter I removed. I purchased a new Honda cabin filter and our van is back to normal. I did not realize how much I missed the auto temperature setting. I was setting the temperature about 5 degrees below "normal" to try and keep the temperature consistent, and it was not during the hotter summer months. Unfortunately I am beyond the 30 day Amazon return window so I am not able to return the cabin air filter. :-( This is my first Amazon review that moved from 5 to 1.....

Reliable part
The price of this item was a bit of a shock. A good one though. I gave it to my mechanic, he installed it with no problems. Runs just fine. Would buy again
