Which Spark Plug - 04 Gt3...?


Recommended Posts

.........perish the thought of having an Indy or worse an OPC change my plugs, (never comfortable with throwing vast sums at labour time for a retentively DIY job) can anyone tell me the regular plug for the 04 GT3, I know there's at least a couple of brands used but which part number, also would like to use my own tried and tested over the years plug (Denso IK22) which I believe is correct for this engine, any thoughts amongst the Renntech massive....??

I need some help with the sparkplug change on a 2005 GT3.

I ordered the part number 999-170-195-90

I received Beru Ultra 14FR-5LDU but I read that Beru Ultra 14FR-6LDU is the common replacement plug.

What is the difference in these plugs? Can I safely use the 5LDC or should I reorder the 6LDC?
