WTB: small size battery

I am looking for recomandation on what battery to use to clear the intercooler coldpipe.
Of if someone know where I can get one of those in the GTA.

just buy a blasted kill switch!!!

Mazda miata battery, im running one and kept my battery in the front you have to make a custom bracket to holld it tho…but its not hard.

Do I have to go to mazda since it’s a special battery? I am sure CT doesn’t carry that on the shelves.
No way I am installing a kill switch outside the car, it’s not a track car.

napa has a size that I made fit. I wish I could remember the number for you.
