I got 5 boxes of BP Plugs . And in 3 boxes the plugs seems to get an issue on the thread . The other 2 boxes the plugs seems to work perfect .
The 3 Boxes with the bad plugs are in grade 6 . The 2 Boxes with the good plugs are grade 7

I dont want to say that its normal ...but shit happens . It was very difficult to discover why the plug leaks and the head gets wet .

Only now I have read the comment of Piston .

I´am from austria . How It seems you are involved in the BP Factory . Nice .

I dont wanted to say that BP is a bad engine . But when I get 3 new engines and because of bad plugs the engine didn´t work well , you maybe can understand that someone gets angry . Because 1000 euro for bad working engines are a lot of money .

But now the issues are dissapeared and I hope the engines will run well for a long time .

I was only dissapointed because I prefer the BP engines and not the Vega .
The BP´s looks awsome and are mancraffted in very high quality .
The Vega is a very strong engine and the engine when I compared it with the BP´s was faster .....But its no wonder when the plugs didn´t fit perfectly.

Now I Hope . Would be pleased when the engines work well . We´ll see .
