BKR5EIX-11 Plugs

Hey guys, been looking around but can't seem to find anything to help...

I've got the opportunity to get a set of NGK 'part# BKR5EIX-11 stock # 5464' at a pretty good price. My question is, while this is not the recommended factory replacement, do you think these are good to use in my 07 WRX? According to Amazon, they would fit and work for my vehicle. Any input from you guys? What's the difference between these and the stock ones? Thanks everyone!

Found this NGK part number decoder pic... for the plugs you're asking about:

B = 14 mm thread diameter
K = hex size 5/8
R = resistor type
5 = heat rating, slightly hotter than you probably want
E = 19 mm thread reach
IX = ?
11 = 1.1 mm (0.044") wide gap, which is a little bigger than you want - that should be regapped to around 0.030"

I'd say probably the most highly recommended plug for your car (and other 06+ WRXs and 04+ STis) would be NGK's LFR6AIX plug, which is stock heat range and made of Iridium. It should provide a good spark and good performance for 60,000 miles on a stock to slightly modded (Stage 2) car.

L = thread reach 26.5 mm (dunno why this is mentioned twice)
F = 19 mm (3/4") reach, 20.6 mm (13/16") hex
R = resistor
6 = stock heat rating, I think
A = firing end construction, ok
IX = ?

No prob.. I'm actually working on organizing the compilation of spark plug info I found when I was researching my own plugs which seems to have some extra answers not found in the Manifesto. Hopefully I'll be able to post it pretty soon.

If you can wait a little bit to order your plugs, it might help to skim through the info I found and see why it's good to stick with stock heat range plugs (6) until you're pretty significantly modded. I'll try to hurry up...
