Upgrade the cooling system of your 2012-2015 Honda Civic Si with this Mishimoto Performance Aluminum Radiator, built to manage the sustained thermal output of a high-revving K-series engine on the street and the track. All-aluminum construction with precision TIG-welded end tanks outlasts the factory plastic-tanked unit prone to cracking under heat cycling and repeated high-rpm use. A 63% increase in core volume over the OEM radiator delivers greater surface area and thermal capacity, keeping coolant temperatures stable during back-to-back pulls, spirited street sessions, and weekend track days where the stock radiator starts to fall behind.----Designed as a direct-fit replacement for the 2012-2015 Honda Civic Si, this radiator drops in without cutting, fabricating, or modifications, and works seamlessly with all stock hoses and components without alteration. The included high-pressure radiator cap maintains optimal system pressure from the first drive, extracting the full benefit of the upgraded core. The Mishimoto Magnetic Drain Plug catches ferrous metallic debris before it circulates through the cooling system, protecting your K-series engine internals and extending service life beyond what the factory setup allows.----Don't wait for your stock radiator to crack and leave you sidelined. Whether you daily drive your Civic Si, push it hard on weekend canyon runs, or are building toward a higher-output K-series setup, this aluminum radiator handles the sustained thermal demands your factory unit was never built for. Proactive cooling upgrades protect your engine investment - and this one is built to outlast it. Backed by the Mishimoto Lifetime Warranty, this Performance Aluminum Radiator is the last cooling upgrade your 2012-2015 Honda Civic Si will ever need.

Spray stops working
Size: 5 Ounce (Pack of 2)
I’ve been buying this product for awhile and keep experiencing issues. It protects your skin well but is sometimes hard to spray and half the time the nozzle stops working while there is still product in the bottle.

Scent: Fragrance Free, Size: 16 Fl Oz (Pack of 2)
I keep a pump bottle of this Babyganics foam sanitizer in my car (along with paper towels). It cleans up my hands well when running errands, leaves behind no residue, perfume or chemical odors.

Great sanitizer
Scent: Fragrance Free, Size: 16 Fl Oz (Pack of 2)
I've been using this product for years. The scent (mandarin) is light and easy on the nose. There's also the unscented one that has no smell at all. Both products gets the job done! The sanitizer is not like the typical alcohol sanitizers. This one is more easy on your hands and it doesn't dry it out. Not to mention it's also foam! It's easy for both adults and kids to use.
