I need to change the NGK plugs in my 2004 ralliart. I would like to go with Denso Iridium. I have been searching on line and everyone including Denso says use Denso IKH20. Can anyone confirm this? The reason I ask is it says those are gaped at .044 the NGK's I believe are gaped around .030. Is this correct and are those Densos the right plugs for the RA? Thanks in advance.

 

From Denso's part finder:

Make: MITSUBISHI
Model: LANCER
Sub Model: RALLIART
Displacement: 2.4
Engine Type: L4
Std Plug No: K20HR-U11
Prem Plug No: N/A
IR Plug No: IKH20
Gap: 0.044

You're right, though, the NGK is gapped smaller:

2004 MITSUBISHI LANCER SPORTBACK 2.4 L4 4G69 FI
Spark Plug Part No. Stock No. Plug Gap
Laser Iridium LZFR6AI 3656 .032


Personally, I prefer the NGK plugs.

 

Summit Racing has the cheapest price I've seen on the NGKs, $7.99 each + ship. Downside, though, is that they (and everyone else) don't keep them in stock, so no matter where you order them from, you'll have to wait a couple weeks.

 

sparkplugs.com, $7.83 each.
Got them within a week last month. Also prefer NGK's. Don't mess with a bigger gap, the OE type NGK's are the best plug for a reason.

I searched the internet and found a coupon for $5 off from the SR20 Forums. 'SR20509' is the code. Not sure if it is still active.

Maybe we can get an EvoM code from them.

 

Just ordered, code's still good, thanks Will!

 

Cheers, mate!

 

good info im sick of 15 bucks a pop at napa

any clue what a E3 cross over would be they sound promising and would like to try em

 

Any spark plug with more than one prong is a gimmick.

 

good to know
