There is a guy selling Denso Iridium plugs for $50 bucks for the set. Sound a bit steep and I don't think any plug is worth that much. I will probably put in the TR-55'* and see how they run.
Do you recommend a spark plug change every year? I don't mind changing plugs but I don't want to waste money either.
How about spark plug wires. What brand and what type do you recommend.
Is it worth swapping wires? Any performance or gas mileage gain?
Thanks for your help! I may attempt a spark plug change this weekend
Those plugs typically sell for around $60 before shipping if I remember correctly. Radrick has good credit around here (notice JimW'* Rora with Bonneville 17" chromies), and $50 with shipping included is a fair price considering to buy them and have them shipped to you would more than likely cost close to $70.
If you do get the TR55'* you won't be dissappointed, but the Denso'* are some nice plugs, but IMO I personally wouldn't get them until I've done further modding as their bang for the buck isn't as big as the TR55'* (Denso'* are BETTER, but the benefit per $ is smaller).
As for changing plugs every year, they aren't cheap and if you've got an extra $13 why not? But if you don't feel the need to and the plugs aren't fouled or anything then all you need to do is pull them clean them and regap them.
For plug wires alot of us liked our Taylor Spiro Pro'* but most of us encountered problem well before they should have had them. Seems now that everyone is getting Belden Premium wires from NAPA as they are only $35-40 and have a lifetime warranty. MSD also makes excellent wires as does Jacobs and Magnacore, but then again they are $15-20 more and aren't worth the miniscule gain over the Belden'*, which is what Rogue runs in his 400+ hp 2000 SSEi.
Between the plugs and wires you might see as much as 3-5 hp and up to .5 mpg in town and 1-2 on the freeway. If you really want to get those gains though I'd suggest a Cold Air Intake (prefabbed for $150-300 or a do it yourselfer can have make their own for under $50) and or a Carsound/Magnaflow 2.5" high flow Catalytic convertor off ebay or www.justmagnaflow.com
($55.74 including shipping).
Glad to help. I'm not the most knowledgeable, but I do my best to help the knowledgeable to share their knowledge.
