Overview:
ACCEL HP 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 HP 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 HP Spark Plugs have machine rolled threads allowing for a more precise thread engagement and torque retention.
Features:
- One Piece Design - Won't break off in head during removal like two piece designs
- The Copper core is a better conductor than Iridium or Platinum plugs
- Copper dissipates heat much better than other materials
- "C" - Cut Design un-shrouds the spark kernel for a better burn
- Unlike Iridium or Platinum plugs, the ACCEL HP plugs are gapable
- Machine rolled threads for precise thread engagement
- One step colder than stock

Excellent Family Passport Holder – Spacious, Secure, and Stylish!
Color: Black Wallet, Color: Black Wallet
I bought this passport holder for my family of five, and it has exceeded my expectations! It easily fits all five of our passports with room to spare — I’m confident it could hold a sixth passport comfortably. The layout is very well thought out, with six card slots, one clear ID slot, and a mesh zippered coin pouch that’s perfect for small items.
There are also two roomy zippered compartments inside that could hold documents, tickets, or even some cash. I love the added features — an exterior slip pocket, a zippered pocket on the outside, and even a spot for a pen (which comes in surprisingly handy when traveling). The wristlet strap is a great bonus, making it easy to carry, and the main zipper closure keeps everything secure.
The material feels durable and nicer than I expected for the price. It looks sleek, holds everything we need for travel, and keeps us organized on the go. I highly recommend this passport holder for anyone traveling with a family — it’s practical, well made, and very affordable.

Great wallet
Color: Black Wallet
These are great wallets; the size is a little big, they are roomy and not bulky. I do get a lot of compliments on the appearance of the style because of the size they are thinner than a bulky leather wallet and your stuff isn't scrunched up inside which makes it easier to locate. Love the look with the different colors and it seems to be a plus because of the card protector. I know they advertise as a vacation wallet but the comfort of the security and with the zipper closure makes it great for everyday use.

Single Passport Holder for Travel, RFID Travel Document Organizer - product as described
Color: B-Single-Lilac Purple
Holds my passport easily and a number of cards/driver's license. Fairly compact. Zipper is a little stiff. I had to zip close & leave it for a while to loosen the spine, shipped flat open.

Family travel document must have
Color: Black Wallet, Color: Black Wallet
I made a last minute call to purchase this travel wallet for my families recent trip to Mexico and I'm glad I did. There is a space for all of our passports, cards and cash and misc travel documents. We were able to stay organized and immediately file away important travel items in one easy pouch. In the hotel the size of the wallet made it easy to store in the hotel safe. The thick durable case also made me feel confident my travel essentials were RFID protected. I will definitely put this to the top of my travel essential list and would highly recommend this product for families, couples and singles for your next trip.
