The most important function of a spark plug wire is to transfer the maximum amount of energy to the plugs, and ultra low resistance, 25 OHM, FireWire does this in spades. What's more, its reactive core construction effectively filters out RFI and EMI "noise" generated by today's high-output ignition systems. This protects on-board computers, instruments and helps preserve audio clarity. FireWire's 8.5mm pure silicone double-layer construction resists the effects of high underhood temperatures and insulation breakdown caused by abrasion. Pure silicone boots are rated to 550 degrees (F). It's designed for use on tube-steel header equipped engines. FireWire is available in custom sets for many popular applications, or in "universal" sets with straight, 1350 and 900 boots for 4, 6 and 8-cylinder engines.

Love these toys!
Color: 4 PCS Ocean Series
My 1 year old pup loves these toys. The clam has been a big hit since it crinkles, has a squeaker "pearl" and a rope. He very proudly brings me this to play with him. Recommend!

Stitching can be weakened by continuous aggressive play.
Color: 4 PCS Ocean Series
Not as tough as touted. I will say that my dog loves the textures and sounds. Safely watching so that it does not shred when toy is ripped. Size was perfect for my 80lb dog. Pet has throughly enjoyed an enjoys the toys.

Tough toys for Chewers
Color: 4 PCS Ocean Series
My dogs love these toys, they are tough on toys so these appear to be well made. I don't expect them to stay in one piece but if they can last more than a week, they are perfect. So far, they have lasted three weeks so this is a record for toys. Cute, and funny to watch pups play with them. Squeaks once in awhile and really cool toys.

Not for aggressive chewers
Color: 1 PCS Salmon
My gsd puppy really liked it but within a few days it started fraying and the strings would get stuck in her mouth. Not for aggressive chewers and not durable.

Dog loved it!
Pattern Name: Pumpkin, Size: Large
This was a fall-themed gift for our friends' large dog. He really liked it -- especially the squeaker -- and enjoyed quietly chewing on it during our visit. By the time we left, it was still in good shape. We've given their dog other chew toys, and they are usually pretty beaten up by the time we leave, but this toy still looked and squeaked fine. No telling what it looks like now, but I can definitely say it survived at least 2 days of heavy dog chewing.
