Plugs for a 9

[m7gsr]

Bro has an issue with his 9 at around 5-6k revs, cuts out. I've not had a chance to drive it yet!

Thinking possibly the plugs, coil packs or worst case clutch on way out. He reckons clutch is fine (I had this issue on a 7).

Can he get away with NGK BPR8ES plugs? Cheaper option than getting the dearer ones to find not the plugs. we can test the coil pack/leads off my 8MR

The plug leads had to be forced over these plugs so took them back out. Current plugs were ok.

Had a look round and found a split boost pipe. All sorted now
