Upgraded Plugs

[Anth]

Can someone recomend some upgraded plugs? thinking of pulling the HP up to around 650 with DMS but before I do I want to change plugs out


I've been looking at NGK that a few tuners use for stage 2 I think ; https://www.ngk.com/product.aspx?zpid=10135

Standard plugs are just fine for Stage 1, just need proper gapping

I got mine stage 1 Apr and got plugs done but mustn’t be gapped properly when the car is ticking over it’s like it has a wee misfire you feel it through the car on tick over

The tuners use NGK race plugs but not sure you linked the right ones.

[Anth]

I'll speak to DMS anyone got a link of plugs that are the correct ones . Gsc what power are you running with map & Any other adjustments done with tune?

[MikeFish]

I think this is the correct type:
R7437-9 - NGK Spark Plug Sparkplug - Type : Racing - R74379 No. 4654

https://www.ebay.co.uk/itm/R7437-9-NGK- ... 1438.l2649

A quick on the forum for R7437 brings up a few hits:

Or site Sponsor Opie Oils sell them for the same price as my ebay link but do a forum discount so go here:

Thank you Mike your a gent.

[Mr Footlong]

Hmm, MRC have quoted me for slightly different plugs when they remap next month. I like Opie, so would like to send some business that way and save a nice bit of cash, any thought on these NGK Racing 4905 plugs they want to go with, compared to the 4654 plugs mentioned above?

Thanks!

[MikeFish]

4905 is what anth linked to in his first post. Maybe they are the ones to go for then. I just quoted what had been posted on here before so may not be the ones of choice.

[Mr Footlong]

Oops, thanks. Ant, can you remember where you were told to go with the 4905 plugs? Based on what I was quoted I would say you are spot on, but I want to be sure too without phoning MRC to confirm, only to then buy them elsewhere cheaper!

Hi mate, I'm sure these had been used in a Litchfield stage 3 build thead and I called the supplier to confirm last week. I'm sure both would do the Job . Are you going straight to stage 2 Footlong? You will have to let me know the results I've been itching for a while for stage one to get the boost a little more aggressive on feed in throttle (I think the c7 misses this a little)

[Mr Footlong]

Yep, going to grab a set thanks. I hardly get to drive the C7 as I bought it for the wife. Not parting with my C5 any time soon and have managed to snag a TC to send away for upgrading for her, but I also work from home and so hardly get to drive anywhere full stop these days....
