Can anyone confirm if these Spark Plugs actually work with our cars, I havent seen nor heard any threads related to this topic.

Attach is the website that sells them and specifies it's applicable for our cars.

13000149 - Leading Plugs

13000150 - Trailing Plugs - OEM Heat

13000151 - Trailing Plugs - Colder

Allthough I know Denso & NGK are the only ones out there for our cars. Though this might be of interest to confirm if true. Can the Greedy Plugs be better than the DENSO's.

They are rebadged NGK plugs, similar to these but stock heat range:



supposedly the design of the electrode will have a better spark. But there is not a chance in hell they are worth the money. Are you boosted? Are you getting spark blowout even with fresh stock plugs? There are cheaper alternatives such as the irridium BR10EIX plug (about $7 each or so), which I run on my 7. It requires a special thin socket to install though.
