The EL2 manifold is called the "explorer" manifold, its also found on AU XR8s. FBTs as well. The lower is different between EF and EL2, the EF lower (HO) has the ports in a straight line, the GT40/Cobra/Explorer lower has them staggered. The EL2/explorer manifolds pop up fairly often, on ebay, here, or over at FFAU.

So will the ef lower take a Edelbrock upper. Same flow pattern,

Fern tree has an explorer manifold for $750 which is around the price i keep seeing them at.

No, not the same pattern. HO is directly comparable to a bunch of 8 straws stuck together. 750 sounds about right for an Explorer.

A stock Cobra upper flows more than a stock Explorer upper.

Yes, but unported the difference in the dyno readouts will be two fifths of bugger all. http://www.andersonfordmotorsport.com/media/intake1.htm I suppose you are saying that porting the gt40 style lower will give greater benefit if used with an untouched cobra upper than with an untouched explorer upper. I still reckon there would be very little difference.

There isn't a huge difference between the stock uppers but it does exist.
Certainly the lower intake is restrictive and does benefit from some porting. I have ported both the upper and lower of mine so as to gain the most from it. These GT40 manifolds all beat the s**t out of the HO manifold though!

True, but flow means nothing without velocity, & averages are only useful for a rough approximation. The weakest link will always let you down (from diyporting.com "If my hair is on fire, and I am standing in a bucket of water, I should be okay"?) According to that chart, the Explorer is clearly the most consistent of the GT40 clan
xr8ute is dead right & as the article suggests, you really are splitting hairs. The difference between these intakes is so marginal on an engine that you don't base your decision on performance. Cut from page 4 on the above AFM article:

If you're going to spending that money, why not get an aftermarket one? I.e. Performer

I'm not going to find a brand new polished explorer manifold for the same price as the cobra if there $350 to $750 second hand here. But the Edelbrock performer II could be any option if its worth the extra $380 unpolished.

Absolutely. Which is where porting is so beneficial to opening up the sharp bends and letting the velocity increase. {DESCRIPTION} Also, considering that Cobra intakes are pretty much around the same price to obtain ( if you know where to look ), grab a Cobra.

There are differences in the explorers to be aware of too. The earlier explorers are EGR and have thicker bosses to the mounting bolts that mate up to the lower half, where as the later non EGR manifolds are thinner and prone to crack. Ive seen an explorer crack through this weakened area on a mates ute, where as my earlier explorer hasnt given any troubles. The finer details are more closely examined on Corral.

Trust me, you dont need to pay anymore than $400 for an explorer upper and lower intake these days. The last three I have watched sell on eBay have all gone for around $350. An that is just in the last 4 weeks. There is one forsale on FordForums.com.au for $550, that has not sold in over a month. Explorer's are popping up for sale more and more often....and the ones that are selling are going for cheap. The days of paying $700+ for an Explorer intake are well and truly over.... Jaysen makes a very good point about EGR. I would expect very few of the Explorer intakes out there have provisions for EGR. Does this mean E-Series will need a chip to disable EGR in the EEC so they do not ping on part throttle? (without an EGR intake) |

Na they dont ping without the EGR, as Ive since had troubles with mine, and it has been bypassed. It now runs more fuel efficiently, and Im still running 32deg BTDC ing advance @1500rpm as set when in diagnostic mode. The earlier EGR Explorers are more easily sourced from the states off 93-96 explorers if Im not mistaken.
