Since alot of people on here seem to be able to find stuff faster than me, was wondering if anyone knew if they make the Bosch Plats 4-ways for the Z's yet. I tried asking a local auto parts place and they said they were car specific and Bosch doesn't make them yet. Is this true? Also if Bosch can't get em are there any other brands that produce a bigger spark that are available now? thanx for the help

 

Almost every Z the only plugs that really worked for the them NGK and that was it.

 

Are you going nitrous? Why do you need to change sparks?

 

WHY +4's

What a waste of cash!

+4's are the biggest scam in town.....

dont they add like 6hp?

 

No one really answered the guy's question. This is not an opinion poll - is Bosch worth it or not - but I would like to know whether the spark plugs can cross-referenced to some other vehicle, so that the inside thread fits. If anyone has any experience with this, please let me know.

 

no, I also think it's just marketing BS.

Denso Iridiums or NGK Iridiums are best.
