Hi can anyone tell me what the correct gap in the spark plugs should be just i have removed my engine and giving it a full check over, have new spark plugs just wanted to know what the gap is as standard plz.

 

Tis ok i have found out 0.7mm or 0.65mm mine are o.7mm so this should be fine.

 

0.7mm for std boost.

Or 0.65mm for upped boost. Go for 0.65 - less chance of misfires...

 

Thanks joz

 

Have you got a Classic? Are you fitting NGK PFR7B plugs?

If not, then you should... lol

 

yes i ahve a classic, i have bought brand new denso ones mate are they crap then lol? was going to ge the ngk's too

 

NGK are std fit and are used by pretty much everyone - including the specialists, etc. If it ain't broke, don't fix it, etc...

PFR6B is std, PFR7B is one level "colder" i.e. has the ability to resist cylinders' heat/pressures better.

 

Humm may have to invest in some joz, where is the best place to buy them from any ideas thanks lee.

 

im getting mine from ebay £20 fror the set

 

Thanks mate i will check this out cheers lee.

 

Yep eBay vendors - Anywhere between £20-30 for all 4.

 

No probs guys, joz btw any chance you know what is up with my fuel pump mate? i have put a post up about it thanks lee.

 

Have you got a link to these plugs? the best I have seen them is £30, every little helps.....

 

Yeah, I thought 20 quid was a bit of a bargain. £30 is the best I've seen too.

 

Are the NGK Iridium IX (BKR7EIX) any better/no different/worse?

 

Theyre not for a classic mate. classic plugs are ngk pfr7s. iirc the ones you posted are maybe for newage..

 

i got these off ebay for mine and have no problems (MY99)
they are 1 grade colder than standard

and camskill's web site has them list for impreza up to 2006

They were recommended by, and I got them from http://www.JP4mance.co.uk
Were they wrong in recommending these instead of the PFR7B's?

(jdm MY95 wagon with with 3" full de-cat turbo back, green panel filter, ported headers (heat wrapped as are downpipe and up-pipe), TD05 with Major Sarcasm ECU upgrade chip.)

 

Go for the PFR7B's IMO.
