Style Posted October 27, 2015 Share Posted October 27, 2015 Hi guys, Got 6 NGK BKR6EIX Iridium Tipped Spark Plugs for sale. Came off my NA-T as I was getting spark blowout when I upped the boost. Only covered around 140 miles. Ideal for BPU according to the servicing guide on here. £35 to your door NOW SOLD Link to comment Share on other sites More sharing options...
r0cknr0lla Posted October 27, 2015 Share Posted October 27, 2015 Hello mate.. What boost did they blowout at? Link to comment Share on other sites More sharing options...
Style Posted October 27, 2015 Author Share Posted October 27, 2015 I was running them fine at 7psi and then I went to 1bar where the misfire came in. I'd suspect they'd be fine to around 12psi on a healthy engine Link to comment Share on other sites More sharing options...
