Where in the uk could i get these

[color=#000000:post_uid5]Hi
As you can tell im from the UK (England) I own a MAZDA 323F 1.8i Executive, with 17" Alloy's.

I would like to find a supplyer here in the UK for BodyKits and other mods for it, eg, induction kit's and exhuast's.

First of all im looking for a Kit so if anyone could help i would be very greatfull

Thanks again

[color=#000000:post_uid0]hey there!

well, i don't know of any UK suppliers, but a couple of European ones are ATH Autosport (http://www.ath-hinsberger.com/) or Pakfeifer (http://www.pakfeifer.at). They both have kits for the 323F BA-shape (94-98). i wouldn't think it would be to hard to import one from either of those places...

or ask the boys over at 323f.net (http://www.323f.net/) :)

cheers

[color=#000000:post_uid0]lawton,

i get each issue of REVS magazine...it's from the UK and 80% of the content is advertising....grab yourself a copy of that and you will be on your way....best of luck.

[color=#000000:post_uid0]Hey guy's thank you very much. :)

I'll let you know

whats the best thing to do first for more proformance?

thanks again[/color:post_uid0]

[color=#000000:post_uid0]I would start with a decent cat-back exhaust, get you some throttle response :)[/color:post_uid0]

[color=#000000:post_uid1]Also some ducting into the std airbox is good. You can
then replace the factory filter with a panel K&N or similar
oiled cloth or foam filter. You can also run high octane
fuel and advance the timing a couple of degrees.
Lastly if its a 94-98 323F you can run MX6 turbo spark plugs
which are extented reach to place the spark a bit further
down in the combustion chamber. The MX5 guys rave that
its good but I didn't notice a difference maybe the other
items masked the gain. Doesn't cost any more for the
plugs and I ran them fine without hitting anything.

[color=#000000:post_uid0]Dear Bigmal,

If you run spark plugs with extended reach, it is very dangerous to advance ignition.
Extended reach plugs are a cheap means of "tuning", but not a good one.
Also every degree extra advance creates a raise in combustion chamber temperature of about 75 degrees.
If you run plugs with long ground electrodes (extended reach), this could be very dangerous.
Also you have the spark on a different position than Mazda intended, you get a different heat distribution.
Turbo engines should not run extended reach plugs.

Better would be to keep the spark on the original position and go for a high performance plug.
Best are NGK or DENSO who also supply the original Mazda plugs.

Example for 323 BA 2.0 V-6:
Original plug NGK BKR6E-11 or DENSO K20PR-U11
Upgrade= NGK BKR6EVX-11 (thin 0.8mm electrode platinum)
Upgrade= DENSO K20PR-ZU11 (thin 0.7mm electrode platinum)
Upgrade= DENSO IK20 (thin 0.4mm electrode iridium)

For continuous high speed driving and a hot climate Mazda also allows plugs with a colder heatrange. These plugs can dissipte heat quicker to the cylinder head, so run cooler.
NGK = heatrange 7, DENSO = heatange 22

For turbo engines, the wear is higher, so in that case longlife plugs can help to keep spark performance for a longer time.

[color=#000000:post_uid1]Hey Michiel,
I agree that chamber temps may rise but wouldn't that be
from a more complete combustion. *From memory higher
octane fuels burn slower so advancing the timing is almost
needed to get them to burn completely.
As for the extended reach plug. *The one I used was a MX6
turbo factory recomended plug. *I haven't used them for a
while but can get the part number. *I was a little concerned
myself so cranked over the motor without starting it to make
sure it didn't hit the piston. *That was on a N/A motor so
would be less of an issue for a turbo motor. I decided to try
them after reading a string of posts on mx5 sites about them
which included dyno runs so if the change in spark placement
was causing a problem with the heat distribution I would
expect it to be picked up with the dynoing. *

Glad to see you questioning the stuff put here.
I am not a mechanic so all the stuff I write is only from
personal experience and would be happy to be proved wrong
before somebody does damage to a car. *However I ran
the plugs for 40k and checked them each time they came out
and no sign of excessive damage from heat or detonation.

[color=#000000:post_uid7]Hello Bigmal,

It's probably the higher octane fuel that is saving you from pre-ignition or detonation problems due to advanced ignition and extended reach spark plugs.

High octane fuels do not necessary burn slower. They just can resist a higher temperature and pressure before they auto-ignite.

If you have no problems, than the plugs work fine in your engine, but please remember that you are starting the combustion on a different place in your combustion chamber than Mazda intended. This means either more thermal load in the head or in the piston (I will have to look this one up)
Also check your old plugs for signs of melting on the tip of the ground electrode.

Depending on the heatrange you are using, you can also use the Mazda plugs from the 323 BG 1.8 turbo
NGK heatrange..6.. or Denso ..20..
K20PR-TP11 = Mazda JE44-18-110

NGK heatrange..7.. or Denso ..22..=colder running plug
K22PR-TP11 = Mazda JE46-18-110

However, the aftermarket plugs will probably be cheaper and specially the iridium plugs with thin centre electrode will work better. They require less Voltage to make a spark and therefore can still spark strong in high boost conditions.

Best regards,

Michiel

[color=#000000:post_uid1]Hey Michiel,
Yes if you are going to advance the timing you must run
high octane 98ron fuel. The extended reach plug is only
about 5mm longer so I dont think it will have the drastic
effect you talk about but it is enough to move it more
into the middle of the combustion chamber. Remember that
our car is made for general use with crap fuel etc so
everything is conservative like timing and suspension etc.
Mazda don't index the spark plugs either but for the
performance enthusiast gains car be had by doing things
like that.

Do a search for Mazda extended plugs and review the results.
Here are a couple. The first one mentions that the extended
electrode produces more power because the tip is less
shrouded.
