i'm currently using stock spark plugs(bkr6e-11) gap at 0.032" on my turbo '99 SiR. i know i should use the bkr7e-11 but i couldn't find one from where i live. the only plug that is available so far is the bpr7es.

can i use the bpr7es? what's the differences between the bkr7e-11, bcpr7es11, and bpr7es?

advanced auto parts has the bkr7e-11s, the part number is 1283, if they try to ask you what car you have tell them it doesnt matter bc its a race motor.

 

the problem is i don't live in the US. i assume advanced auto is in the US so shipping will cost an arm and a leg to asia. that's why i like to know if there are any differences with the bcpr7es11 or bpr7es coz i might try looking for those 2 at the same time. by the way, a friend told me that there's a shop here that sells the bpr7es.

 

bkr7e-11 = 14mm thread, Hex 5/8 Projected tip ISO, Resistor type, 19 mm reach, temp 7. Pregapped at 1.1mm.

bcpr7es-11 = 14mm thread, Hex 5/8, projected insulator type, Resistor type, 19 mm reach, Standard 2.5mm dia electrode, temp 7. Pregapped at 1.1mm.

bpr7es = 14 mm thread, Projected insulator type, Resistor type, 19 mm reach, Standard 2.5mm dia electrode, temp 7.

So, looking at the full descriptions, all three designs will work in your application. All three are very similiar. Minor differences are the tip projection (ISO or not), and the electrode diameter and shape which is a don't care most of the time.

You can interchange anyone as identical replacements for you.

I really needed to know this, Thanks!! I have three different sets of 7 range plugs.

 

thanks man.

 

i came across a NGK plug BCP7ES without R(resistor type) would that fit a 99SiR? does it matter if there's an R or not in the BCP7ES?
