h22a turbo sparkplugs/ - Honda Forum / Acura Forum

hey i looked around but didnt find anything for my setup, i either found other turbo cars or h22 sparkplugs but i was wondering what kind of sparkplugs should i go for and what kind of sparkplugs wire i should use i dont thing OEM will be good so i personally dont have a clue to what to go for.

i have an h22a turbo and putting 9psi (if it really make a difference on which sparkplugs / wires i should get)

thanks for the input in advance.

NGK one step colder than stock.

NGK R5672A-10 if you can get them

Hey thanks you guys, and now im still wondering what wires to get would any do?

thanks for the advice in advance.

oh how i love my coilpacks hehe

MSD's aren't bad, but if you do buy wires such as MSD or what not make sure you get a kit where you can cut them to length. Though it may be a bit more trouble than just having some uneven wire lengths it will look much cleaner and fit exactly as you want it to.

Theres a few places on the net that make 0 ohm plug wires, and can custom make you a set if your into some high price stuff.

Granatelli makes 0 ohm wire, you could probably order their wire and just take apart the stock wires you have, reuse the old fasteners and have exactly what you want.

Whats the resistance of the current wires on your car? Resistance causes the output voltage to decrease, under higher boost it becomes much more difficult for a spark to generate in the combustion chamber.

For plugs I would go with an iridium either NGK or Denso, they have finer center electrodes and will produce a spark more easily than traditional spark plugs. IMO Bosh suck, don't use them.

Indexing your spark plugs wouldn't be a bad idea either. removing the washers that come with plugs can sink them deeper into the combustion chamber as well, which can potentialy lead to a better combustion.

IIRC - the ground strap should be on the intake side of the combustion chamber, theoreticly this creates the best flame front for us. This will keep gas from directly spraying onto the electrodes, supposedly keeping them cleaner and allowing a better spark. since the ground strap will be in the way its also supposed to keep the spark from "blowing out". You can buy indexing washers at most automotive stores.

Hey thanks for the for the GOOD advice and yeah i went with the exact plugs that holloway mention i just copy and pasted the exact number the put down and i bough them from sparkplugs.com they are good price but the shipping cost as much as the plugs. Well right now im not really sure what wires are on my car because my cusin owned the car before my which he bought as is from auction and he did the tune up to it. And he bough wires that are aftermarket ones but my cusin isnt into import so i dont think he knew what to put on there.

Well thanks for the advice again

Bosch wires are usually about 1500-3000 ohms per wire for their "performance" oem replacements. IF you know how to use a digital multi meter, measure the resistance of your sparkplug wires. If your still using factory coils and distributor, I would reccomend MSD's, or the ebay "low resistance" wires arent that bad either, but they sometimes require soem modifications.

i was always told the best ignition system for a honda is the stock one. i don't know how that pertains to wires, but the stock ignition system has been proven to over 400whp. just food for thought

Well from an electrical standpoint, Honda's ignition systems are made for their OEM setup, not with an intention to be modified heavily with forced induction.

A thought to consider is when you reduce the amount of resistance in a circuit you will increase the flow of electricity. What I wonder about is if you increase the flow of electricity by changing to a extremely low resistance plug wire and increase the work the stock ignition must now do, will it be able to keep up with the extra flow demand of the circuit without losing the voltage needed for proper ignition? Especially in higher RPM situations. The higher the RPM and the lower the resistance of the circuit the harder it is for the stock ignition to keep up with the current demands.

This is why I think new plug wires are good for NA applications and MSD or other aftermarket higher power ignition systems + good aftermarket wires can be more essential in a boosted environment. Even more so the higher your Revs go, since the energy demand will be considerably more.

As for stock plug wires, mine were up there for resistance, longest one was approaching 12k ohms, where as new MSD wires were like 130 ohms for the longest one. This can cause a significant voltage drop, and combined with a loose fitting connection to the spark plug + spark plugs often built in resistance, and the ever increasing gap while the spark plug is in use, you can really see where replacing stock gear could benefit your overall performance over time.

EDIT: Oh yea coil packs can kick much ass. Although you can upgrade them as well

from what i have seen msd has caused nothing but issues on non-race spec hondas. stock igition and fuel rail are good for considerable power

I see what your saying, and most of the time I'm betting someone didn't use common sense while installing their items.

Without a detailed bit of information about the ignition system you can't make a real viable argument of saying if it needs replaced or not. After a while though high voltage systems can start to break down. So original OEM gear could eventually put out weak sparking power. A comparison of a BRAND NEW oem ignition VS an MSD setup would be nice to see on a dyno with a boosted H22 like his though.

I think unless your making a lot of HP beyond stock you don't need to upgrade your ignition. As for plug wires, just measuring the resistance, and comparing it to OEM replacements should tell you if your wires need replaced.

Currently im running MSD wires and I like them. Though there are some length issues, its not a big deal. I have seen far worse. Better too long than too short, cause I can trim them down later to make the fit "perfect"

exactly. i'm a firm believer. "if it ain't broken then don't fix it"
