Ngk Iridium spark plugs x6
These plugs are tried and tested (including in our personal 1Jz's), they offer great performance and value.
The three heat ranges listed will cover most Jz's but please get in touch if you have more specific requirements.
Use heat range 6 on stock engines or ones with slight modifications including upped boost levels (stock turbo to around 1 bar).
Heat range 7 is for more modified engines above what is described for heat 6.
Heat range 8 would be used in cars running top mounts and high horsepower circa 500bhp.
We are more than happy to dicuss which heat range will suit your needs if you're unsure.
Please be aware there are many cheaper Chinese copies on the market being sold through various channels by lots of sellers, the copy plugs are well known for dropping tips. These plugs are genuine Ngk plugs, we wouldn't accept the copy plug!
Please use the drop down box to select your vehicle and heat range.
