Hi Guys

Need to change plugs in my Rocc. Which are the best plugs to use and where can I buy from?

Thanks

BKR7EIX from KAR @ R550
BCPR7EIX from Mooloo but he has no stock
Try Yosh @ unitronic too.

Shot Ruan!

Are these the colder plugs? and if so, is there any benefit on a stock car, or a stage 1 car?

In theory they should help with timing pull so yeah

0.8 gap i think

& 0.7 modded

So just to confirm, it would be benificial in a stock/stage 1 polo GTI, but needs to be gapped to 0.8.

Then once more modding is done, then its better when gapped to 0.7?

What would the benefit be of colder plugs? sorry for the noob question

Just stick to 0.7 from the start. Colder plugs = less timing pull and better fuel efficiency.

The main reason for the guys running colder plugs is to prevent pre-ignition.
Once a motor has been modded the boost fuel and timing is increased, this in turn increases the combustion temps. By using a colder plug with a smaller plug gap helps prevent detination (Pinging). When a motor starts to Ping the ECU pulls timing to stop the pining. You can run a colder plug on your motor , it will help.
