TO DETERMINE WHICH PEAK & HOLD YOU NEED
- Grab a multi-meter and select Ohms 200
- Touch the positive and negative leads of multi-meter together to measure resistance (record this number...i.e. measured 0.3)
- Then take the positive and negative leads from multi-meter and put on each terminal of the injector. Doesn't matter the order. Record this measurement
- Take the ohms measurement from Step 3 and then subtract the number you got in Step 2 (i.e. Step 3 4.8ohms - Step 2 0.3ohms = Total 4.5ohms)
High Impedance Injectors - Above 7ohms - No Peak and Hold Boxes are needed.
Peak and Hold 2A - 3ohms to 7ohms (Bosch 160lb/hr).
Peak and Hold 4A - Below 3ohms to 1.5ohms.
Peak and Hold 8A - Below 1.5ohms (Billet Atomizer*).
All low impedance Billet Atomizer Injectors manufactured after Nov. 2012 require 8A regardless of measured resistance.
*Billet Atomizer Injectors - Anything prior to serial # C300**** should only use the 4A/1A. This only applies to injectors manufactured prior to Nov. 2012.

No Fuss For Kids
Style: Sunscreen Stick, Size: 1.5 Ounce (Pack of 1)
Neutrogena Sunscreen Stick SPF 50 – A Summer Must-Have!
I absolutely love the Neutrogena Sunscreen Stick SPF 50 — it’s a staple in our summer routine. I always keep several on hand: one in the car, one in the stroller, and one in our beach bag. It’s just so convenient to have wherever we go!
What makes this sunscreen stick stand out is how easy it is to apply, especially on my kids’ faces. There’s no mess, no fuss, and no need to rub it in. I can quickly swipe it on even when they’re squirming or in the middle of playing. It goes on clear, feels lightweight, and doesn't leave a sticky or greasy residue.
This product gives me peace of mind knowing my kids are protected with broad-spectrum SPF 50, and I don’t have to wrestle them into a full sunscreen routine. Total win for busy parents!
Highly recommend for anyone looking for a quick, reliable, and kid-friendly sunscreen solution.

I keep buying this every summer for its ease of application! I’ve gotten others hooked on it too. It’s a little greasy but super effective, so worth it!

Convenient product but not worth the money versus regular sunscreen. Good for convenience
Style: Sunscreen Stick, Size: 1.5 Ounce (Pack of 1)

Dermatologist recommended
Style: Sunscreen Stick, Size: 1.5 Ounce (Pack of 1)
I did a light study on these products and this one is recommended by dermatologist with lots of good reason. There’s one dermatologist on you tube that does the most extensive and short, to the point at the same time, explanation of the different products on the market and what you want in a sunscreen. It’s worth looking it up if you used a lot of this product. She wasn’t selling anything but suggested this as one that’s the safest to use you should look that one up if it’s a concern. It’s the best and most simplified piece that I’ve seen on the subject. I recommend this one because that doctor recommended it. I still tan with it but I don’t burn. My pasty white skin likes to burn lol. It stays on with water reasonably well. I like the small package. It lasts pretty good too. I try to travel light and things like this really help. With a light load towel and a few things compact I can carry everything in a very small gym bag. This compact packing is awesome. The speedstick type applicator. The whole thing isn’t just perfect and a great product overall

Silky Smooth
Style: Sunscreen Stick, Size: 1.5 Ounce (Pack of 1)
Silky smooth texture, goes on easily and works well. Feels a little thick and greasy but not as much as other brands.
