i use BCPR6E for my 1.9, ACE!!!!! thou i jusT got some new ones got given BCPR6ES... juts notcied now

 

wonder if theres any diff between the two?

[Andrwn8304 0]

The difference in the E type and the ES type is the S means standard.

 

 

That link should explain a bit more.

the platinum equivalent (EVX i think) is good in the std 1.9; v expensive though

 

i've only ever used the std gap (31thou)

ah so its all about the V-Groove plugs, the BCPR6ES is standard wheres the BCPR6E, has this V-Groove in it?

 

u reckon what is says make much diff?

 

what other NGK plugs could i used which are better than the BCPR6E?

 

faz85 use's BCPR7ES? again whats the diff? again it has the ES on the end, so its standard, but instead of the BCPR"6"ES it has a "7"

The 6 and 7 numbers are the heat range for the spark plug.

 

The plug gap should be 0.7 mm - 0.8 mm 28000 to 30000 I would recommend the 0.7 mm as this saves on the strength of the HT from the coil pack.

 

You can use either just different manufacturers come up with different designs to improve performance.

I use Bosch Platinum in mine, sry not sure on the numbers now.

 

Heres the Champion numbers with the NGK cross reference :-

 

(Champion) - RC7YCC - (NGK) - BCPR7ES

so the NGK - BCPR7ES are better than the BCPR6E? dont like champion, find them very expensive for what they are, and always had problems with them!!!

or the BCPR7E there a slightly hotter plug but designed for the Pugs

so if i got the BCPR7E, would i see a difference in performance from the BCPR6E,S

 

also would the BCPR7E damage my engine?

[Andrwn8304 0]

The performance difference would be so small you wouldnt notice it.

 

Absolutely not they are the plugs listed for your car.

[Spiky 37]

i think i got BKR6EZ

 

so maybe i'll change to BCPR7E and gap to 0.7

IIRC, the "6" rated plugs are the recommended NGKs if you have a catalytic converter. Before doing away with my CAT, I was running BCPR6ES. I switched to 7ES, and there was no noticeable difference really, so its entirely up to you. Either 6 or 7 plugs wont cause you any problems.

i may take back the BCPR6ES I was given back and try a set of BCPR7E, if they dont have any of them i will try the same but ES version

 

ace

 

wonder if i notcie the diff as my leads are proper old and my cap is and the sparks been on a year now, notcied my car is getting slugish, so trying this, normally works!!!!

 

still looking for some leads, i hate bosch leads, always come apart, so looking at ebay now........

 

wish me luck

[saveloy 8]

What you really want is a set of NGK BCP7EV plugs, gapped to 0.9mm, and I mean it. Bingo.

[richard 0]

good choice Saveloy. This is the same gap as i.

[Spiky 37]

where do you guys buy these plug?

 

NGK BCP7EV

 

any local motor factors? or on the net? or pug dealers?

 

any idea on rough price

[309PUG 2 1 Cars]

Just to confuse you even more, I use BOSCH FR7DC+8 recommended by AB Motorsport, thats all they use. Spot on for me, I think Halfrauds even sell them make sure you get the +8 though.

I think bottom line is m8 everyone has there own preferences.

 

If in doubt ask your local motor factor for the top spec plug for your car.

they're OE for some Saabs - you might be able to find them at Motorfactors

 

expensive though - i think £25 for the last set i bought

[Spiky 37]

well my motor factors dont sell BCP7EV nor can they get them

 

so will try halfords next

 

if not ebay sell them at around £5-£6 each

My local Halfords stock them. Excellent plugs, I used them on my TT for years. They are a projected core design, which means the spark is closer to the chamber centre. So, aiding combustion.

It is even worth gapping them to 1mm first and seeing if the engine runs with no mis - fires.

The heat range is the operating temperature of the spark plug and environment, in an XU engine you wont really notice the differences in ranges, (only really noticeable in high output/ high stressed engines) just remember doing a customers car with poor cold starting and running, and it was down to someone fitting incorrect heat range plugs!

[Craigb 2]

excuse my ignorance , but what is the benefit of the larger gap ?
