has anyone here with a 383 hsrm
setup ever used e3 plugs

my car is a 88 gta 305 tpi 5 speed stock

now its a built 383 alum heads everything

I have been watcinh a lot of youtube videos showing 12hp at 350 hp v8 level

I just asking

ty

 

Just run a normal copper plug. Platinum plugs are good when the plugs are hard to access to change. I don't think any low end performance gains justify the extra cost of a high end spark plug.

If you change your copper plugs every few years like you're suppose to, they'll work just fine. Copper plugs are designed to last about 2 years. Platinum plugs are designed to last about 5 years.

You could get 12 HP (claimed) by changing a dirty air filter to a clean K&N too.

** EDIT** My mistake. I thought the E3 were a platinum plug but it looks like they are still a copper plug so not as expensive as the platinums.

Sure. If you can get the plug in the proper heat range for your engine then go for it.

** EDIT 2 ** Just looked up the price. amazon.ca has the E3 to replace my NGK race plugs at $11.54 each. My NGK race plugs are about $3 each from the local Napa dealer. Personally, I don't think it's worth the extra expense.

 

 

E-3s are not worth it at all.

 

Waste of money.

Just use NGK or ACDelco copper plugs.

ok im using copper ac delcos now

I was just curious

have you all watched the youtube videos showing hp gain on a dyno??????

 

 

All kinds of things can give HP gains. $100 for a claimed 12 dyno HP isn't that great considering not all engines are the same. I doubt you would even feel that extra HP with the butt dyno.

If you were racing in a class where every tiny percentage of HP gain is worth any cost then it's a good deal. For the average street car, it isn't.
I laugh at all the big name racing claims for the plugs. Of course they're going to give credit to the plugs. They're a sponsor. They probably could have won with NGK plugs as well. When you look at top fuel, they use up 16 spark plugs in one 1/4 mile pass. That's a lot of spark plugs to use over a weekend of racing.

As mentioned above, E3 plugs can not change the gap. I also look at the design and I can see issues if you need to index the plugs. My plugs are all indexed. If the ground strap was at the bottom, the piston would hit it. The E3 ground strap is huge with very little opening to have facing downward.

 

Would you trade off 12 HP, for sitting by the side of the road with a PO'ed member of the desired sex TO YOU in the pass seat? (I'd say "a PO'ed girl/woman" but what do I know...)

Yes: Then E3 plugs are FOR YOU.
No: Avoid ALL "gimmick" plugs and stick with OEM types. AC/Delco, Motorcraft/Autolite, Champion, Denso, NGK, Bosch. No matter what the brand on the box, just look it up for your car, and if it's the one that fits, go with it.

A stock 305 in your year would use something like AC R44TS or R45TS, or the nearest equivalent in ANY of the other world-wide OEM brands as listed above. AVOID gimmick plugs like E3, +4, etc. No particularly good reason to put anything other than the OE AC/Delco in it unless they're out of stock. You won't get ANY horsepucker out of any of em.

 

My last set (last month) of Delco R45TS were made in China. I didnt notice till after I installed them and saw it on the delco box. I'd check the country of origin first before buying any plugs.

 

So? I use NGK race plugs and they're not made in North America.

 

I just installed a set of Accel shorty non-resistor copper plugs in my 86 TPI and they are working excellent. Doubt they are USA. It's what I could get local and I needed them right away. Just drove 800 miles over Christmas in my TA and cruising the interstate at 85 MPH was fabulous. I shortened up a Craftsman 5/8 spark plug socket on my lathe, removed the rubber insulator and was able to get to each plug with my Dyno Don headers.

Accel, last I knew, was actually Denso, just private-labelled. Good plugs.

 

Good idea, i just use a 5/8 1/2" drive socket and weld on a nut on the end.
It's just the right length.

 

Not saying you have to buy North American made products, just warning others about checking delco plugs, since my last set was made in Mexico and NOS made in USA ones are available regularly on ebay for less then the Chinese ones in the local parts stores. But hey, if you want to support China, that's your choice.
