NITROUS OXIDE ( nos / n2o ) advice forum

Ok.. so after various discussions on here I have been assured that a WON kit will not blow up my engine, and im about to order a kit for my car... but!

im a little worried about spark plugs.

As standard my car (year 2009 Fiesta 1.6) is fitted with spark plugs that i cant seem to find a cooler plug for, maybe you guys can help?

The std plugs are Bosch HR8MCV or the NGK equivalent is TR5-B13 I am currently running Nippon Denso ITV-16 iridium.

heres a picture I took of the std Bosch plug compared with the Nippon Denso Iridium plug.



could any of you kind folk point me in the direction of a cooler plug, which i understand is essential for nitrous use before i buy a WON kit.

also im gonna have a crack at fitting the kit my self... theres no where local to me who fits them, and its a hassle leaving your car with someone having to arrange lifts etc etc.

thanks in advance

Gimme a bit of time to research for you

thanks your a gent

The unusual (now becoming more popular) reach of the plugs really do narrow choices down but I did find an NGK solution: LTR6IX part no. 6509

These plugs are 1 step harder than stock. The projected fine-wire iridium tip could cause issues on larger shots than 50, but I can't say for sure as I haven't tested these on nitrous yet. I do have a set in my possession that i want to try Trev's mod on to see if it could work on nitrous as well as a standard nitrous plug.

But you'll be just fine with up to 50 with these plugs.

Ack, I don't have a pair of those plugs like I thought, I have some that are similar but standard core. If I do come across some, I'll do some testing on those some time in the future.

Thanks for your help it is most appreciated

I think i have found a set on Ebay... they are listed as LTR6IX-11 though, would that be the same?

The -11 is just a code for the pregap.

I should caution you that there are KNOCK OFF NGK plugs out there and especially from ebay so I would source a reputable NGK retailer for your purchase.

Thanks again for your help

I do believe ive located a colder denso iridium too.... http://www.ebay.co.uk/itm/DENSO-Iridium ... SwwE5WXG1j

its a shame locating a colder copper core spark plug isnt throwing up anything

I haven't any experience with Denso, I only use NGK primarily. Either way, you'd still be fine with even a fixed 50 on them.

Ive ordered the Denso itv20 plugs, ive used both ngk and Denso before in the past as well as Bosch and Champion.

Ive had Denso iridium plugs in my current car for the past 10 months and i am pretty impressed with them.

Ok i have the money for a wizards of nos kit... can anyone point me in the direction of a kit?

Trevor ( if you are there)i dont mind driving up to your place to buy it off you and have it professionally fitted if you think you can do it in a day?

yes that looks very much like my engine.

Heres a photo of my exact engine...



and the car 2009 Ford mk7 Fiesta zetec s...



I have replaced the exhaust system with a full Milltek system including replacing the restrictive exhaust manifold with cat built in with this:





I now have a 200 cell sport cat mounted where the middle silencer used to be.

Trevor did say some time ago the exhaust system will help the nitrous work better.

This is the reason why i would prefer a professional install, I very nearly bought a brand new WON kit off e-bay last night, imagine the calamity if i had attempted to fit it my self and it wasnt even the correct one for my car

I have been thinking about the refill problem, and was thinking along the lines of having a spare bottle, so when i empty one, i can fit the other then i have some time to get a refill... probably the better idea will be to eventually have a big bottle stored in my shed so i can do my own refills.

but i wanted to have a little time to get used to nitrous first... powerwise im thinking initially a fixed 25 shot untill i get used to nitrous, then add a controller and go for a 50 shot.

im sure the car will cope with a 50 shot, i have fitted bigger brakes, stiffer suspension and the chassis is very competent, when the car was released motoring pundits commented the chassis is very good and feels like the car needs more power!

of course i will wait and see what Trevors opinion is on my ideas.... and of course if my engine is suitable for nitrous... I hope the plastic inlet manifold isnt going to pose a problem too ?

Phew!!! so glad I didnt hit buy now on e-bay last night and waited for some expert advise...

I seem to have somehow missed all this thread, don't know why it's not informing me of your posts but better late than never.

OK dealing with the plugs first the rules are these;

1) DON'T WASTE your money on fancy plugs, it's all sales HYPE.
2) NEVER use any brand other than NGK and no they don't sponsor me and I don't stock any brand of plug, although they did used to sponsor a race event that I ran some years ago.
3) STOCK copper core plugs are more than adequate.
4) Unless you intend to use the nitrous for more than a hundred yard or so bursts most STOCK plugs should be OK up to 75 HP of nitrous. We normally give a figure of 50 HP because most customers tend to do some kind of 1/4 mile racing and we like a bit of safety margin
5) If you can't get a harder grade plug in the cheap stock type, just cut back the ground/earth strap a few mm but make sure you do it as per the instructions in my book.

We INITIALLY supply ALL our under 3,000 cc customers with 25 HP jets and increase from there as required. With regards to this particular vehicle engine/manifold arrangement, we've had MANY customers with this type of vehicle and 50 HP has been enough to satisfy even the most mental of street racers, plus pushing it to 75 gets it a bit close to the limit of the pistons, so 50 keeps everyone happy and there's no need to modify ANY parts. Anything above 50 would require a DP system (due to the upturn in the manifold from the TB to the inlet valves), so again running with 50 keeps the system cost lower and fitting easier. Adding a progressive makes it easier on your engine and safer in general, as well as elevating the amount of power you can safely add and put to good use.

There's no problem with using 'fancy' plugs if there's no other alternative.

Ha ha why does everyone always associate ebay with dodgyness and counterfeit goods

The won kit i nearly bought was brand new from power house in sheffield, who are a won agent...

I wouldnt buy a 2nd hand nos kit however cheap and deffo not from someone without very good credentials.

BTW... Do you have a smartphone with video recording or a small camera? I'd like to get some videos / photos of your car before the install and after the install; especially, the first hit on the lovely nectar. I want to start making a database of videos of WON customers and their first reactions to that first nitrous experience as well as a brief overview of his or her vehicle. Would you be interested?

Which is why I made my statement that the comment I made in response to that was NOT aimed at you in BOLD.

It just reminded me of what 'OTHERS' have done.

For your interest Alex, I've been having one of my team gather all our pics and videos (from our YouTube channel, Facebook, Forum, etc.) and add them to our Website picture and video pages, so you might like to check for updates.

Already in the database

I'm looking into finding another flavor of videos with people's first experiences using nitrous, especially that first ear-to-ear grin

If I can 'grasp' the positive experience of being a new nitrous user, then perhaps others may be more willing to dip their toes into the WON world.

You must have read my mind turbo box...

i was thinking of doing a little video so everyone
Can put a face to my forum name, it might only be
A low budget affair though, i dont have anything fancy to film it on and im not much use at editing... might rope my son into helping

so just to clarify... as im a little confused

would this be the nitrous kit I need for my particular engine... http://www.noswizard.com/car-nitrous-ki ... -body.html

and the nitrous/fuel nozzle would be mounted into the blue pipe in between the air filter and throttle body butterfly ?
