Your cart is empty.ACCEL's "Shorty" spark plugs keep your spark plug boots from being burned and your headers from being dented if you don't have enough room between your plug boots and your exhaust manifold or headers. Designed for trouble-free installation and removal in cramped spaces, these high-performance plugs are much easier than OE plugs to get a socket on but still deliver a larger, hotter, fuller flash front and significantly more power at high rpm. You'll have instant throttle response and better fuel economy with less fouling, flame dissipation, and misfire. These copper-core plugs provide increased thermal conductivity, come with machine-rolled 14mm threads to protect your heads, use a standard 5/8 socket, and come in a pack of eight.

Used for a big block Chevy engine in a 1972 Nova with headers. Cleared the headers just fine and the heat range is about perfect for a daily driver. Clean fuel burning. I would use these again.

Spark plugs going into a hot rod application with very little clearance. These plugs fit beautifully and work well. Highly recommended.

Shorter than standard plugs. Better wire clearance and less burning and shorting out

Product is as listed. To clear some headers these are a much. These plugs should fit all small block chevy engines such as the 305, 327, 350. These are one of the hotter burning accel short plugs. I run a msd ignition and they handle the extra voltage just fine.I have no problem with this product. It is suitable for stock engine and higher horsepower engines as well.

Perfect replacement for my 91 F150 with the 302. Works nicely with my new long tubes, but didn't see much of an improvement over the Motorcraft plugs I took out that were at least a year old, that was a small disappointment but they work better for my new exhaust setup so I'm happy

these are not U-groove plugs, they are short header style regular plugs and are from the Czech Republic, not Japan
