BCPR6ES are a great plug for the price ($3)... They will suit standard boost fine and will take the occasional thrashing... You may possibly be able to run the standard 1.1mm gap depending on the health of your coils and the boost pressure your using...
The PFR*A's will work fine but are a platinum plug so budget around $20 per plug... The advantage is they will last up to 100,000 k's as opposed to the BCPR's which are copper and should be changed every 10,000 - 15,000 k's...
