We’ve joined forces with some of our valued customers to tackle the challenge of radiator and cooler protection and have developed the Radiator Plug and Cap Starter Pack.

Inside, you’ll find a mix of 10 different cap and plug sizes, each conveniently bundled in sets of 100. We’ve handpicked these sizes based on their performance in covering those critical drain holes and pipe ends. This means your radiators and coolers get the protection they need during storage, stay secure during transportation, and hold their resale value.

Sometimes you might come across an oddball size. No problem! Just measure the inside diameter of the hole or the outside diameter of the pipe you need to cover. Then, hop over to our Mid-point table using the link below to find the closest match.

Once you’ve nailed down the size you need, it’s as simple as clicking this link: Tapered Caps and Plugs. Use the dropdown menu to choose the right SP part number, and you’re good to go.

We hope this makes your engine protection journey smoother. And for your convenience, we’ve included a printable Cap/Plug Selector table below, so you’ll have a handy reference when it’s time to place your order.
