I did a search and didn't come up with anything useful...

Whats the difference between the ZFR7f-11 and BCPR7es-11 ???

Which one is better for boost on a b18b?

Thanks in advance!

 

use the zfr7f11 is made fo the ls and the gsr uses the bcpr7es11 the vtec motors at least but either plug will be fine. part number is 1095 on the bcpr7es11 if you need them i ahve baout 30 sets

 

I use ngk pt # 1095 (bcp's)

However the other plugs will work fine too.

 

I personally use the ZFR's but hey If they have used the other ones and they work then hell whatever one they have in stock use those. Or use the ZFR's then next set use the other NGK's and form your own opinion.

Later,

i normally use the zfr's but alot of people say that they use the bcpr's. i was just wondering if i should switch... last time i pulled my plugs, they came out pure black so i'm in need of replacements soon. anyone one else with an opinion?

BCPR7 is designed for LS
BKRE7 is designed for GS-R

it's the right plugs for the applications...

the -11 at the end indicated the gap recommend it by NGK..

if it doesn't have any -11 at the end, the recommended plug gap is between .028 to .034". If it does have -11 at the end, it is recommended to gap them .036 to .045

you can buy either one and gap it to .030 which is what I run...both the -11 and the plain ends will work just fine...

Actualy stan the zfr5f11 is the true plug for the LS motors. If you stay with the zf sereis two steps colder is 7f11

176-5229/1095 is the Beck/Arnley number for the BCPR7ES-11 plugs.

 

Just get some ngk bkr7e spark plugs because lot of people here say to use them on turbo cars!
