    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

Can spark plugs cause power loss at certain RPMs?

Fortunately that is not the case. There is enough gap between the piston top and plug tip.

A BPR8 type plug has a projected tip in comparison to a B8 so I hope you did not smack the piston with your spark plug tip.

Do NGK dp8ea-9's match with NGK B8ES and NGK dp7ea-9's with NGK B7es? Any suggestions guys?

Couldn't find a decent supplier locally. :| Even the so-called NGK dealers do not have these spark plugs and they refused to import since I wasn't ready to buy more than a thousand pieces from them. The next time I'll hit the market I'll probably be looking for other alternatives like Denso W24ES-U's.

Thanks for the info bro. Actually I've seen some modern alternatives being regularly introduced by spark plug companies so was wondering if there exists a newer alternative of B8ES which I am unaware of. Everywhere I see only platinum, iridium, "awsomenium" spark plugs for "better spark" and "better fuel economy" but no genuine old school reliable parts.

The D-series NGK's are smaller diameter threads than the B-series.

Did you look though that spark plug cross reference guide posted earlier? There are something like 75 interchangeable plugs for you to choose from. You telling us that none of these are available? It's okay to move up to platinum or what have you, just get the size and heat range correct and you should be good to go.
 
The local market here is filled with high heat range plugs. Not enough parts available here easily. I'm looking forward to import me some from US or Japan.

Finally got NGK B8ES Solid from a local seller. New out of old stock. Now all power loss problems seem to be solved and she is running SWEET as hell on higher rpms. ;) (Price per plug: 130 PKR = $1.32) I've bought myself 10 of these. keeping 4 other pairs in my spare box.

$5.99??! :eek: That's WAY too expensive! Man these parts are cheap in my country. The hard part is to find them but once I do, they are as cheap as it can get.
